Question

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

Answer 1

you didnt state if its a parallel or a series circuit

Step-by-step 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

`resistance \: in \: parrall \: (total) = ( (1)/(4) + (1)/(6) + (1)/(2)) ^( - 1) \\ rt = ((3 + 2 + 6)/(12) ) ^( - 1) \\ rt = ( (11)/(12) ) ^( - 1) \\ rt = (12)/(11) \\ rt = 1.09ohms`
