Question

a cell is connected to gohm resistance because of which heat of 400 j Is produced per second due to current flowing through it obtain the potential difference applied across the resistance​

Answer 1

Answer:  

60 Volt

Explanation:

here, H = 400 J

R = 9 ohm

t = 1 s

v = potential difference

we know,

from joule's law

so, the potential difference is 60 V
