Physics · Current Electricity
Two resistors A (resistance r) and B (resistance 3r) are connected in parallel. This combination is connected in series to two other resistors C (resistance r) and D (resistance 3r) and a battery of EMF E of n egligible internal resistance. Let PB and PD be the rate of energy dissipated in resistors B and D, respectively. Then the ratio (PD/PB) is:
