Explanation:

1.

(a) By this statement we understand that the appliance uses a power of 60W when it is supplied a voltage of 150V

(b) We need to find current now

Power = Voltage× Current

Current = 60W/150V

Current = 0.4 Ampere

2.

The power is given to be 1.5kW or 1500W

Time given is 1800 sec or 1/2 hours

Energy consumed= Power × time

Energy = 1.5KW × 1/2hrs

Energy = 0.75 Kilo watt hour

Energy in joules= 2.7×10^6 J

3.

Total electrical consumption = 12kWh per day

Rate =Rs 6.25 per unit

Total days = 30

Total rate = 12 × 30 × 6.25

Total rate for 30 days = Rs 2250
