If the potential difference across a 30.0-ohm resistor is 10.0 volts, what is the current through the resistor? O A 0.25 A
OB 3.0 A
OC 0.33 A
OD. 0.50 A

C 0.33 A

Explanation:

The current through the resistor can be calculated using the formula;

V = IR

Where; V = Voltage (volts)

I = Current (Ampere)

R = Resistance (Ohms)

According to this question, I = ?, V = 10.0volts, R = 30.0ohms

V = IR

I = V/R

I = 10/30

I = 0.33A

Hence, the current through the resistor is 0.33A
