1. Given :  5 bulb of 100 watt lighted 6 hour daily

6 fan 50 watt used for 10 hour daily

1 fridge of a of 300 watt used for 24 hour daily

1 Tv of hundred watt used for 10 hour daily

1 heater of 2 kilowatt to used for 2 hour daily

cost of 1 unit is 6

To Find : what is the maximum power when all the appliance used at a time   electrical energy consumed for 30 days

find the cost of

safe rating of electrical fuse​

Solution:

5 bulb of 100 watt   = 5 * 100  = 500 W   in 1 day = 500 * 6 = 3000 Wh

6 fan 50 watt = 6 * 50 = 300W   in a day = 300 * 10 = 3000Wh

1 fridge of a of 300 watt  = 300W   in a day  = 300 * 24 = 7200 Wh

1 Tv of hundred watt   = 100W  in a day  = 100 * 10 = 1000 Wh

1 heater of 2 kilowatt  = 2000W  in a day  = 2000 * 2 = 4000Wh

maximum power when all the appliance used at a time =

500 + 300 + 300 + 100 + 2000  = 3200W  = 3.2kW

Voltage rating = 220V

Current = 14.54 A

safe rating of electrical fuse​  = 16 A

in a day = 3000 + 3000 + 7200 + 1000  + 4000

= 18200 Wh

= 18.2 kWh

= 18.2  units

cost of 1 unit is 6

Hence total cost = 18.2 * 6  = 109.2  Rs
