In the circuit below, R1 = 4 Ohms, R2 = 6 Ohms, and R3 = 2 Ohms. The total resistance of the circuit is Ohms.

you didnt state if its a parallel or a series circuit

Explanation:

if in series

add the Resistance

Rt = R1 + R2 + R3

Rt = 4 + 6 + 2

Rt = 12ohms

however if in parallel.

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

1= 26.17

2= 1.17

3=30.86

4=5.86

just took the assigment on edge

reserve is the answer
