Problem:

Given

V_T = 12V

R₁ = 1kW

R₂ = 2kW

Determine

I_T

I_R1

I_R2

Procedure:

1. Find the total resistance

R_T = R₁ + R2

R_T= 1k + 2k

R_T = 3kW

2. Calculate the total current

I_T = V_T = 12 = 4mA

R_T 3k

3. Determine the current for each resistor

I_R1 = I_R2 = I_T = 4mA

An important characteristic of series circuits is that the same amount of current flows through each element of the circuit, including the source and all resistors.

Solution

I_T = 4mA

I_R1 = 4mA

I_R2 = 4mA
