Answer:

R = 0.6 ohms

Explanation:

We have,

Voltage of the circuit is 12 V

Current flowing in the circuit is 20 A

It is required to find the resistance of the circuit. Ohm'slaw gives the relationship between voltage, current and resistance. It is given by :

[tex]V=IR[/tex]

R = resistance

[tex]R=\dfrac{V}{I}\\\\R=\dfrac{12}{20}\\\\R=0.6\ \Omega[/tex]

so, the resistance of the circuit is 0.6 ohms.
