Within 30 days, the house consumed 33000W * h of electricity. What current flowed through the circuit when it was turned on, if it was turned on for an average of 5 hours every day?
Given:
W = 33000 W * h – the amount of energy that was consumed in the house during the time interval t;
t = 30 days – time interval;
n = 5 hours / day – operating hours of electrical appliances per day;
U = 220 Volts – the voltage of the home electrical network
It is required to determine I (Ampere) – what value of current flowed through the circuit.
Let’s find the number of hours per month during which electrical appliances were working:
N = t * n = 30 * 5 = 150 hours.
Then their consumed electrical power is equal to:
W1 = W / N = 33000/150 = 220 watts.
The current strength will be equal to:
I = W1 / U = 220/220 = 1 Ampere.
Answer: on average, a current of 1 Ampere flowed through the circuit.
