Question

if a typical family of four uses electric energy at an average rate of 700 w , how many kwh would their electric bill show for one month (30 days)?

Answer 1

P(ower) = 700 w = .7 kw 1000 w = 1 kw

E = P * t = .7 kw * 24hr = 16.8 kwh in one day

E (30 da) = 16.8 kwh / day * 30 day / mo = 504 kwh / month
