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.
Prelab Exercises: 1. Calculate the resistance (in ohms) of a resistor that is part of a circuit with a voltage of 5V and a current of 940 mA. 2. Given the following resistor, decode its resistance value using the Electronic Color Code link given on the previous page: 3.

As you may have guessed from the name, an LED is a diode that emits light when current flows through it. Each kind of LED takes a specific voltage to light up, usually between 0.5V and 2V.
