If NEPA charges 5k per kWhr, what is the cost of operating for 24 hours a lamp required 1A on a 200v line?

it meant to divide the value like this 1 x 200 x 24 / 1000 inorder to convert is to kwhr do that you re going to get 4.8 as they did there so it typographical error

Power = current * voltage
current = 1A voltage = 200v
P = 1 * 200 = 200watts
convert to kilowatts
200/1000 = 0.2Kw
Energy = power * time
E = 0.2 * 24
E = 4.8Kwh
since 1Kwh is 5kobo
4.8*5 = 24kobo

to calculate the cost;
cost=energy consumption (e) ×rate(r)
energy consumption (e)=po
