Question

A 12-ohm resistor is connected in series with a 23-ohm resistor. They are placed across a 120-volt power source. What is the current in the circuit?

A) 35 amps

B) 10 amps

C) 5.2 amps

D) 3.4 amps

Answer 1

3.43 A

Step-by-step explanation:

Applying,

V = IR'.............. Equation 1

Where V = Voltage, I = current, R' = Total resistance

Make I the subject of the equation

I = V/R'........... Equation 2

From the question

Given: V = 120 volt, R' = (12+23) = 35 0hm

Substitute these values into equation 2

I = 120/35

I = 3.43 A
