A dryer runs on 240 V with a resistance of 30.0 Ω. What is the current of the dryer?

Current, I = 8 Amps

Explanation:

Ohm's law states that at constant temperature, the current flowing in an electrical circuit is directly proportional to the voltage applied across the two points and inversely proportional to the resistance in the electrical circuit.

Mathematically, Ohm's law is given by the formula;

Where;

V represents voltage measured in voltage.

I represents current measured in amperes.

R represents resistance measured in ohms.

Given the following data;

Resistance, R = 30 ohms

Voltage, V = 240V

To find the current;

Current, I = 8 Amps

Therefore, the current of the dryer is 8 Amperes.
