Question

A battery having e.m.f 5V and internal resistance 0.5 ohm is connected with a resistance of 4.5ohm then the voltage at terminal of battery is ....

Answer 1

Answer:

VOLTAGE=EMF-CURRENT X INTERNAL RESISTANCE

I= 1A

V=5 - 1 x 0.5

V=4.5 volts

Answer 2

Answer:

4.5 V

Explanation:

i=R+rE

=4.5+0.55

=1 A

V=E−ir

=5−1×0.5

=4.5 Volt
