Chooe the correct anwer about the circuit to how how to calculate the reitance of the lamp. (Parallel circuit which ha a 12V battery, 2. 2A and a 10ohm reitor)
-The potential difference acro the lamp i 1. 2 V. -The current at Y through the lamp i 2. 0 A. -The current at X through the reitor R i 1. 2 A. -The reitance of the lamp i 10 Ω
