Mathematics · Current Electricity - Resistor Networks
Two resistors A (resistance r) and B (resistance 2r) are connected in parallel. This combination is connected in series with two other resistors C (resistance r) and D (resistance 2r) and a battery of EMF E with negligible internal resistance. Let PA and PC be the rate of energy dissipated in resistors A and C, respectively. Then the ratio (PC / PA) is:
