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.
Resistance--measured in ohms, the basic unit of electrical resistance--is the opposition to the flow of free electrons in a circuit. Measuring the DC resistance through a transformer's winding is an easy way to judge the condition of a transformer without applying power to it.nstructions. Disconnect the transformer from the circuit before testing it. A transformer's winding forms a parallel connection with the circuit, and unless you disconnect at least one leg, you will get a false reading. Set up the DMM to read resistance and select an appropriate resistance range.
