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.
In a small silicon diode operating at its rated currents, the voltage drop is about 0.6 to 0.7 volts. The value is different for other diode typesâSchottky diodes can be rated as low as 0.2 V, germanium diodes 0.25 to 0.3 V, and red or blue light-emitting diodes (LEDs) can have values of 1.4 V and 4.0 V respectively.
