Answer 1

Answer:

1) led 3v battery consumes about 17 lakh rupees around India and 17v battery around 13 lakh

Answer 2

Answer:

First , we know

P(W) = V(V) × I(A)

Watt = Volt × Current

You need to know how much Current is passing through that Bulb . Then you will come to Know the Watt.

Power consumption is dependent on the ratings of LED.

If I take an example of 10 watt LED.

10 watt=0.01 kW

Then

Unit consumed =kW × Total hour in a month = 0.01 × 360

Unit consumed = 3.6 kwh

★ Now find the Rate of Electricity in your Area and Multiply it by Unit Consumption . You will Get Your Answer in Indian Currency.
