Question

Two conducting wires of the same material and of equal lengths and equal diameters are first connected in series and then parallel in a circuit across the same potential difference. The ratio of heat produced in series and parallel combinations would be -

please explain ​

Answer 1

Resistance R is inversely proportional to the heat produced in the circuit. Find the equivalent resistance of the wires when connected in series and parallel. Apply the formula of electrical power(heat produced).
