Using Nitroglycerin for Angina - Topic Overview To improve blood flow to the heart, nitroglycerin opens up (dilates) the arteries in the heart (coronary arteries), which improves symptoms and reduces how hard the heart has to work. Nitroglycerin comes in quick-acting forms and long-acting forms.

How Does a Transistor Work: Transistor Basics A bipolar transistor needs to be differentiated from a field effect transistor. A bipolar transistor gains its name from the fact that it uses both holes and electrons in its operation. Field effect transistors are unipolar devices using one or either type of charge carrier. A bipolar transistor, or more exactly a bipolar junction transistor, BJT, has two diode junctions which are back to back.

How Circuit Breakers Work Circuit Breaker: At Work in Your Home. The power distribution grid delivers electricity from a power plant to your house. Inside your house, the electric charge moves in a large circuit, which is composed of many smaller circuits. One end of the circuit, the hot wire, leads to the power plant. The other end, called the neutral wire, leads to ground.

- Although the MOSFET is a four-terminal device with source (S), gate (G), drain (D), and body (B) terminals, the body (or substrate) of the MOSFET is often connected to the source terminal, making it a three-terminal device like other field-effect transistors.n the case of an n-type switch, the body is connected to the most negative supply (usually GND) and the gate is used as the switch control. Whenever the gate voltage exceeds the source voltage by at least a threshold voltage, the MOSFET conducts. The higher the voltage, the more the MOSFET can conduct.

How Circuits Work Take the simple case of an electric light. Two wires connect to the light. For electrons to do their job in producing light, there must be a complete circuit so they can flow through the light bulb and then back out. The diagram above shows a simple circuit of a flashlight with a battery at one end and a flashlight bulb at the other end.

What are âSeriesâ and âParallelâ Circuits? There are two basic ways in which to connect more than two circuit components: series and parallel. First, an example of a series circuit: Here, we have three resistors (labeled R 1, R 2, and R 3), connected in a long chain from one terminal of the battery to the other.

Logic gate With amplification, logic gates can be cascaded in the same way that Boolean functions can be composed, allowing the construction of a physical model of all of Boolean logic, and therefore, all of the algorithms and mathematics that can be described with Boolean logic.

logic gate (AND, OR, XOR, NOT, NAND, NOR and XNOR) Its output is true if the inputs are the same, andfalse if the inputs are different. XNOR gate. Using combinations of logic gates, complex operations can be performed. In theory, there is no limit to the number of gates that can be arrayed together in a single device.

Lessons In Electric Circuits -- Volume I The Mesh Current Method, also known as the Loop Current Method, is quite similar to the Branch Current method in that it uses simultaneous equations, Kirchhoff's Voltage Law, and Ohm's Law to determine unknown currents in a network.ust plug in that other value for the load resistor into the Thevenin equivalent circuit and a little bit of series circuit calculation will give you the result. 1  REVIEW: 2  Thevenin's Theorem is a way to reduce a network to an equivalent circuit composed of a single voltage source, series resistance, and series load.

How do transistors work? Answer. The design of a transistor allows it to function as an amplifier or a switch. This is accomplished by using a small amount of electricity to control a gate on a much larger supply of electricity, much like turning a valve to control a supply of water. Transistors are composed of three parts ï¿½ a base, a collector, and an emitter. The base is the gate controller device for the larger electrical supply. The collector is the larger electrical supply, and the emitter is the outlet for that supply.

How Amplifiers Work How Amplifiers Work. The component at the heart of most amplifiers is the transistor. The main elements in a transistor are semiconductors, materials with varying ability to conduct electric current. Typically, a semiconductor is made of a poor conductor, such as silicon, that has had impurities (atoms of another material) added to it.

Superposition Example The voltage and current measured by the meters are the outputs or responses of the circuit.The principle of superposition says that the response of a linear circuit to several inputs working together is equal to the sum of the response of that circuit to the inputs working separately. In this example, let.or example, use the scrollbars to set I. 1  The meters indicate that I=-2.5 A and V=45 V. 2  Left-click on the current source to remove it from the circuit. 3  Left-click on the current source to restore it to the circuit. 4  Left-click on the voltage source to remove it from the circuit. 5  The principle of superposition predicts that.

Voltage and Current When a voltage source is connected to a circuit, the voltage will cause a uniform flow of electrons through that circuit called a current. In a single (one loop) circuit, the amount of current at any point is the same as the amount of current at any other point.

What Is an Electronic Circuit? In other words, a circuit must form a loop. An electronic circuit and an electrical circuit has the same definition, but electronic circuits tend to be low voltage circuits. For example, a simple circuit may include two components: a battery and a lamp.

- A circuit is like a road - it provides a path that electrons can flow through. In a series circuit, that 'road' for electron movement is a single pathway that connects devices in series, one after another in a row. When we say a circuit is closed, this describes a circuit with current flowing through it.

Learning about Logic Gates and Circuits Digital logic circuits are one particular application of boolean logic that uses voltage values to represent true and false, or 1 and 0, if you prefer. Boolean logic simulators can simulate electronic logic gates in an interactive environment on your computer.

FHSST Physics/Electricity/Circuits An important principle to realize here is that it doesn't matter where the break occurs. Any discontinuity in the circuit will prevent electron flow throughout the entire circuit. A combination of batteries and conductors with other components is called an electric circuit or circuit. The word circuit implies that you return to your starting point and this is an important property of electric circuits. They must contain a closed loop before charge can flow. The simplest possible circuit is a battery with a single conductor. Now how do we form a closed loop with these two components? The battery has two terminals (connection points).

How Transistors Work EyesWideOpen/Getty Images. Transistors are devices that control the movement of electrons, and consequently, electricity. They work something like a water faucet -- not only do they start and stop the flow of a current, but they also control the amount of the current. With electricity, transistors can both switch or amplify electronic signals, letting you control current moving through a circuit board with precision.
