Question

An ideal battery provides a voltage of 24.00 V and delivers a constant current of 2.37 mA to an appliance. How much work does the battery do in three minutes?

Answer 1

Work done by battery will be equal to 10.238 J

Step-by-step explanation:

We have given ideal an ideal battery with ideal voltage V = 24 volt

Constant current
`i=2.37mA=2.37* 10^(-3)A`

Resistance will be equal to
`R=(V)/(i)=(24)/(2.37* 10^(-3))=10126.58ohm`

Time is given t = 3 minutes = 3×60 = 180 sec

We have to find work done by battery

Work done is equal to
`W=i^2Rt=(2.37* 10^(-3))^2* 10126.58* 180=10.238J`

So work done by battery will be equal to 10.238 J
