An electrical circuit consists of a DC battery and a single resistor. If the battery has a voltage of 12.0 volts and a current of 4.00 amps flows through the circuit, what is the resistance of the resistor? 400 Ohms 120 Ohms 4.00 Ohms 3.00 Ohms 12.0 Ohms

Answer :

Given

Voltage is V=12.0 V

Current is I=4.00 A

To find

The resistance of the resistor

Explanation

By Ohm's law,

[tex]\begin{gathered} V=RI \\ \Rightarrow12=R\times4 \\ \Rightarrow R=3\text{ ohm} \end{gathered}[/tex]

Conclusion

The resistance is 3 ohm
