Question

drive the expression for effective resistance and three resistor are connected in parallel
​

Answer 1

Explanation:

Laws of resistance in parallel: (i) Voltage across each resistor is same and is equal to the applied voltage. (ii) Total current = sum of the currents through the individual resistances. (iii) Currents through various resistance are inversely proportional to the individual resistances.

Answer 2

Explanation:

hope it works out
