Question

100 kilo joules of energy flows in one minute forty seconds in an electric device of resistance forty ohms . Calculate the potential difference . Calculate the resistance of device

Answer 1

60 is the potential difference

Answer 2

Answer:

20v

Explanation:

h= 100 kj

h= 100000j

r=40ohm

t= 100 sec

v=?

I = √H/Rt (under root mein H divide by R multiply t

so √10000/4000

= 5A

V=IR

5*4= 20 v.
