The current running through a circuit is 10 amps from a 5 V battery. Calculate the resistance.

a. 0.5 Ohms
b. 2 Ohms
c. Not enough information
d. 50 Ohms

To calculate resistance, you can use Ohm's Law:

Resistance (R) = Voltage (V) / Current (I)

Given that the voltage is 5 V and the current is 10 A, we can plug these values into the equation:

R = 5 V / 10 A
R = 0.5 Ohms

Therefore, the correct answer is:

a. 0.5 Ohms
