Question

a resistance of 25 omega is connected to a 12v battery . calculate the heat energy in joules generate by pet minute ​

Answer 1

Answer:

The heat energy in joules is 345.6Joules.

Explanation:

Given Problem:

A resistance of 25 ohm is connected to a 12 V battery . calculate the heat energy in joules generated per m

Solution:

To Find:

Heat energy produced.

---------------------

Method:

Current = $\frac{V}{R}$

= $\frac{12}{25}$ = 0.48 ampere.

Heat energy:

⇒ I2Rt

= (0.48)2 x 25 x 60

= 345.6 Joules. .........(Answer)
