Answer : The voltage of the battery in the circuit is, 15 volts
Solution : Given,
Resistance = 3 ohms
Electric current = 5 ampere
Using ohm's law,
[tex]V=I\times R[/tex]
where,
V = applied voltage
I = electric current
R = resistance
Now put all the given values in this formula, we get the
[tex]V=(5Ampere)\times (3ohms)=15volts[/tex]
Therefore, the voltage of the battery in the circuit is, 15 volts
