In the direct current circuit U = 220, I = 5A. Determine the power of the consumer and the consumption

In the direct current circuit U = 220, I = 5A. Determine the power of the consumer and the consumption of electricity for 8 hours of work.

In a direct current circuit U = 220 V, I = 5 A. We need to determine the consumer’s power and electricity consumption for 8 hours of operation, i.e. e. find P and A.
We find the power of the consumer using the following formula:
P = U * I.
Let’s find the power of the consumer:
P = U * I = 220 * 5 = 1100 W = 1.1 kW.
Using the power of the consumer and time, we find the power consumption, where P = 1100 W = 1.1 kW and t = 8 h = 28800 s:
A = P * t = U * I * t = 1100 * 28800 = 3168000 J. (8.8 kWh).
Answer: P = 1100 W = 1.1 kW and A = 3168000 J = 8.8 kW. h.
