Question

A voltage of 12 V is applied across a circuit with one 3 0hm resistor in series and three 3 Ohm resistors in parallel. What is the total current in the first 3 Ohm resistor in the circuit? The total current of the circuit is 3 A

Answer 1

First let's draw a diagram of the circuit:

Since the total current is the same current that passes through the series resistance, therefore the current in the first 3 ohms resistor is equal to 3 A.
