A transformer is connected to 120 volts. Find the current if the resistance is 480

ohms.

0.25A

Explanation:

Data obtained from the question include:

V (Voltage) = 120v

R (Resistance) = 480 ohms

I (current) = ?

Using V = IR, the current flowing can be obtained as illustrated below:

V = IR

I = V / R

I = 120/480

I = 0.25A

Therefore, the current flowing is 0.25A

Answer: 0.25 amperes

Explanation:

Given that:

Voltage of transformer = 120 volts.

current = ?

resistance = 480 ohms.

Recall that voltage is a product of current flowing in the circuit by resistance.

i. e Voltage = curent x resistance

120 volts = current x 480 ohms

Current = 120v/480 ohms

= 0.25 amperes

Thus, the current in the transformer is 0.25 amperes
