Question

5. Derive the condition for effective resistance, when three resistors are connected (a) in series and (b) in parallel.​

Answer 1

Explanation:

As all the three resistors have been connected between the same two points A and B, voltage V across each of them is same. By Ohm's law, ... (iv) Reciprocal of equivalent resistance = sum of reciprocals of individual resistances. (v) Equivalent resistance is less than the smallest individual resistance
