Initial data: I (current in the lamp taken) = 0.5 A; U (voltage at the terminals of the lamp taken) = 75 V.
The resistance of the lamp taken will be equal to the ratio of the voltage at its terminals and the current strength: R = U / I.
Calculation: R = 75 / 0.5 = 150 Ohm.
Answer: The resistance of the lamp taken is equal to 150 ohms.
