Question

You are given three circuits. Identify the circuit with the minimum dissipation of heat.

KnowledgeBoat · Accepted Answer

For circuit (I) : Net Resistance (R) = 3 Ω Voltage (V) = 6 V Heat Dissipated = P = W .......... (1) For circuit (II) : As resistances are in parallel combination and also have equal value then So, net resistance (R) = Ω Voltage (V) = 6V Heat Dissipated = P = W .......... (2) For circuit (III) : As resistances are in series combination then So, net resistance (R) = 5 Ω Voltage (V) = 6V Heat Dissipated = P = W .......... (3) From (1), (2) and (3) it is clearly visible that in circuit (iii) heat dissipation is minimum.
