Someone's normal heart rate depends on things like the person's age and whether he or she leads an active lifestyle. The resting heart rate decreases as people get older. Typical normal resting heart rate ranges are: babies (birth to 3 months of age): 100â150 beats per minute.
Part of the Electronics glossary: A resistor is an electrical component that limits or regulates the flow of electrical current in an electronic circuit. Resistors can also be used to provide a specific voltage for an active device such as a transistor. All other factors being equal, in a direct-current (DC) circuit, the current through a resistor is inversely proportional to its resistance, and directly proportional to the voltage across it.
Resistor [edit]. A resistor is a block or material that limits the flow of current. The greater the resistance, the lower the current will be, assuming the same voltage imposed on the resistor. The hydraulic analogy of a resistor would be the pipe with water flowing through it.esistance is a characteristic of Resistor indicates the measurement of current opposition. Resistance has a symbol R measured in Ohm (Ï) . The ratio of voltage to current is referred to as Ohm's Law, and is one of the most basic laws that govern electronics.
