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.
You can measure resistance of an electronic circuit using an ohmmeter, which is a standard feature found in most multimeters. The procedure is simple: First, you disconnect all voltage sources from the circuit; then, you touch the ohmmeterâs two probes to the ends of the circuit and read the resistance (in ohms) on the meter. Resistance is measured in units called ohms, represented by the Greek letter omega (Ï). The standard definition of one ohm is simple: Itâs the amount of resistance required to allow one ampere of current to flow when one volt of potential is applied to the circuit.
