Computer science is a discipline that spans theory and practice. It requires thinking both in abstract terms and in concrete terms. Computer Science is practiced by mathematicians, scientists and engineers. Mathematics, the origins of Computer Science, provides reason and logic.
Diode Resistance Formula. The resistance of diodes is equal to the below formula: Diode resistance is equal to the thermal voltage, VT, divided by the current, Id, passing through the diode. The thermal voltage of the diode is approximately 25mV at 300K, which is a temperature that is very close to room temperature. The precise formula to calculate thermal voltage is: VT= kT/q.
An ammeter measures the voltage across a resistor with a known value, and. from that it calculates the current through the resistor. The resistor has to be. a very small value, so that it doesn't change the current in the circuit by being. placed in line with it.o use it, open (break) the circuit whose current you want to. measure, and connect your meter into the hole. Read the voltmeter. The. current passing through your resistor is. (the voltmeter reading) divided by (the resistance of your resistor).
