The Air conditioner unit in the classroom uses 120 volts. it requires 2000 watts of usage on the average, and it stays on for 8 hours every day. Find out the Amps, Watt hrs/Day, Watts hrs/yr, Kilowatt Hrs/Yr and cost/Yr if the cost of elelctricity per kilowatt is $0.25

Step-by-step explanation:

P = IV

2000 W = I (120 V)

I = 16.7 A

P = E/t

P = (2000 W * 8 hr) / (1 day)

P = 16,000 W·hr/day

P = 16000 W·hr/day * (365 day / yr)

P = 5,840,000 W·hr/yr

P = 5,840,000 W·hr/yr * (1 kW / 1000 W)

P = 5840 kW·hr/yr

C = 5840 kW·hr/yr * (0.25 $/kW/hr)

C = $1460/yr
