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.
Every material has an electrical resistance and it is the reason that the conductor give out heat when the current passes through it. Resistance is a measure of how much an object opposes the passage of electrons. The unit of electrical resistance is the ohm and it is represented by Î©. Every material has Resistance. Copper has a low resistance and wood has a high resistance. For example, a metre of copper has a resistance of only 1 Ohm but a metre of wood has a resistance of 10000000 ohm
