Determine the resistance of the filament lamp spiral if a current of 0.12 A flows through it at a voltage at the ends of the network equal to 120 V
These tasks: I (the current that flows through the spiral of the taken incandescent lamp) = 0.12 A; U (voltage at the ends of the network) = 120 V.
The resistance of the spiral of the taken incandescent lamp is calculated by the formula: R = U / I.
Calculation: R = 120 / 0.12 = 1000 Ohm or 1 kOhm.
Answer: The coil of the taken incandescent lamp has a resistance of 1 kOhm.
