Physics · Current Electricity
Three resistors A (resistance r), B (resistance 2r) and C (resistance 3r) are connected in parallel. This combination is connected in series to three other resistors D (resistance r), F (resistance 2r) and G (resistance 3r) and a battery of EMF E (negligible internal resistance). Let PC and PG be the rate of energy dissipated in resistors C and G, respectively. Then the ratio (PC/ PG) is:
- 14/121✓
- 25/311
- 32/31
- 43/51
Correct answer
4/121
