Tanner · Answer 1

Answer: 2.0 ohms

Explanation:

Given that,

Voltage (V) = 12V

current (I) = 6A

resistance (R) = ?

Since, voltage, resistance and current are involved, apply the formula for ohms law:

V = I x R

Make R the subject formula

R = V / I

R = 12V / 6A

R = 2.0 ohms

Thus, the resistance will be 2.0 ohms.
