an electrical appliance take 5A when operated on a 220V supply. If the appliance is operated from 6am - 6am at 10kobo per KWh how much will d nepa officer collect?
An electric appliance take 5A when operated on a 220v supply.find the cost of operating the appliance for 12 hours at 10 kobo per kwh
oops, it runs for 24 hours..
=(220*5)(24*3600)(10 ) Kobo
cost=power*timeInSeconds*cost/kwh
=(220*5)(12*3600)(10 ) Kobo
I don't know can someone help me please
To calculate how much the NEPA officer will collect, we need to determine the power consumption of the appliance in kilowatts (kW) and the duration of its operation.
The power consumption (P) of the appliance can be calculated using the formula:
P = V × I
where V is the voltage (220V) and I is the current (5A).
P = 220V × 5A = 1100W (watts)
To convert the power consumption to kilowatts (kW), we divide by 1000:
P = 1100W ÷ 1000 = 1.1 kW
Next, we need to determine the duration of operation. Since the appliance is operated from 6am to 6am, we have a 24-hour period.
Now, let's calculate the energy consumption (E) in kilowatt-hours (kWh) using the formula:
E = P × t
where t is the duration of operation in hours.
E = 1.1 kW × 24 hours = 26.4 kWh
The cost of electricity can be calculated by multiplying the energy consumption by the cost per kilowatt-hour:
Cost = E × Price
Price is given as 10 kobo per kWh. Converting 10 kobo to naira, we have 0.10 NGN.
Cost = 26.4 kWh × 0.10 NGN/kWh = 2.64 NGN
Therefore, the NEPA officer will collect 2.64 Naira for operating the appliance from 6am to 6am at a rate of 10 kobo per kilowatt-hour.
