Answer:

Its effective resistance at the rated voltage would be from P = E²/R. So R = E²/P = 144/36 = 4Ω. Current is E/R = 12/4 = 3A. Now you need to drop 8 volts at 3 amps. R = E/I = 8/3 = 2.7Ω.

Just to check - total resistance is 2.7 + 4 = 6.7 ohms. Total voltage 20 V so current is 3 amps. Power in lamp with 12 volts and 3 amps = 12 × 3 = 36 W
