Question

17) A 6 ohm resistor is connected to a battery of 12V. The heat energy dissipated in 1
minute is
a) 432J
b) 25920J
c) 30J
d) 1 440J​

Answer 1

Explanation:

given R= 6ohm

V=12v

t= 1 min= 60 s

according to the equation,

H=V²×t/R

=(12)²×60 / 6

=1440 J

so the answer is d option 1440J

hope you got the answer
