Question

8) A cell is connected to a 9 ohm resistance, because of which heat of 400 J is produced
per second due to current flowing through it. Obtain the potential difference app lied across
the resistance.
(3M)​

Answer 1

Answer:

the potential difference is 60 volts

Explanation:

Heat H= i2Rt = vit=v2 t/R

400= (v2/9)×1

v2 = 3600= 60×60

therefore v=60 volts
