The electric motor connected to the 120 V network worked for 6 hours. energy consumption during this time was 0.8 kWh. calculate the current consumed by the electric motor.
Initial data: U (voltage in the network to which the electric motor is connected) = 120 V; t (duration of the electric motor) = 6 hours; W (energy consumption during the operation of the electric motor) = 0.8 kW * h (800 W * h).
The current consumed by the electric motor can be expressed from the formula: W = P * t = U * I * t, whence I = W / (U * t).
Calculation: I = 800 / (120 * 6) = 1.11 A.
Answer: The electric motor draws a current of 1.11 A.
