120 V

5.003 10.093 15.003

Equivalent resistance: 2.73 Ω

Voltage: 120 V

Total current: 44 A

Explanation:

In the figure attached, the circuit is shown

The equivalent resistance (Rt) is calculated as follows:

1/Rt = 1/R1 + 1/R2 + 1/R3

where R1, R2 and R3 are the individual resistances. Replacing with R1 = 5 Ω, R2 = 10 Ω and R3 = 15 Ω, we get:

1/Rt = 1/5 + 1/10 + 1/15

1/Rt = 5.5/15

Rt = 15/5.5 = 2.73 Ω

From the picture, the voltage in the circuit is 120V

From Ohm's law:

It = V/Rt

where It is the total current, V is the voltage and Rt is the equivalent resistance

It = 120*5.5/15 = 44 A
