Question

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

Answer 1

Answer:

V=IR

12=I(25)

I=0.48A

P=VI

=12 x 0.48

=5.76J

Since power is energy/sec,

Power/min = 5.76J x 60s = 345.6J

**

Given => R = 25 ohm

V = 12 Volt

T = 1 min = 60 sec

To Find => H = ?

I = ?

********

Current = V / R= 12 / 25 = 0.48 ampere

Heat energy = I²RT= (0.48)² x 25 x 60 = 345.6 Joules
