Theory of Operation of Resistor

Ohm's law:

The behavior of an ideal resistor is dictated by the relationship specified in
Ohm's law

V = IR

Ohm's law states that the voltage (V) across a resistor is proportional to the current (I) through it where the constant of proportionality is the resistance(R)


Series and parallel resistors:







Resistors in a parallel configuration each have the same potential difference voltage.To(find their total equivalent resistance(Req



















The current through resistors in series stays the same, but the voltage across each resistor can be different. The sum of the potential differences (voltage) is equal to the total voltage. To find their total resistance
