(a) State Ohm's law. Write formula for the equivalent resistance Rp of the parallel combination of three resistors of values R1, R2 and R3.
(b) Find the resistance of the following network of resistors :
Solution
(a) Ohm's Law – The potential difference, V, across the ends of a given metallic wire in an electric circuit is directly proportional to the current flowing through it, provided its temperature remains the same.
Formula :- $\dfrac{1}{Rp}$ = $\dfrac{1}{R1}$ + $\dfrac{1}{R2}$ + $\dfrac{1}{R3}$
(b) R + R/2 = 3R/2
