Three resistors A (4 Ω), B (6 Ω), and C (12 Ω) are connected in parallel. This combination is connected in series with three other resistors D (4 Ω), F (6 Ω), and G (12 Ω) across a 12 V battery of negligible internal resistance. If PA and PD represent the rate of energy dissipation in resistors A and D respectively, then the ratio PA/PD is:
- 11/8
- 21/4✓
- 32/3
- 41/2
Correct answer
1/4
