The following three resistors (Ohms) are in parallel with one voltage source. What is the total current running through circuit?

Battery 4
Resistor A 5
Resistor B 4
Resistor C 7

Explanation:

The total resistance Rt is given by

1/Rt = 1/Ra + 1/Rb + 1/Rc = 1/5 + 1/4 + 1/7 = 0.593

or Rt = 1.69 ohms

The total current I running through the circuit is

I = V/Rt = 2.37 A
