Answer:

The resistance of the appliance is 30Ω.

Explanation:

In our case, we are to solve for the resistance of an appliance where the current connected to the voltage source was given. Here, we are going to apply Ohm's law where the voltage is directly proportional to the current and resistance.

The formula for Ohm's law is:

V = IR

where

V     is the voltage, unit is in volts, V

I       is the current, unit is in amperes, A

R      is the resistance, unit is in ohms, Ω

For the given information

I = 4 A

V = 120 V

R = ?

Solving the problem

Let us use the Ohm's law formula  and substitute the given information, we have:

V = IR

120 V = 4A (R)

Divide both sides of the equation by 4A, we have:

R = 120V / 4A

R = 30Ω

Therefore, the resistance of the appliance is 30Ω.
