Question

What is the effective resistance for a parallel circuit containing a 12 V potential and three resistors R1= 3 ohms,

R2=2 ohms and R3= 1 ohm.

Answer 1

Gives

R₁=3ohm

R₂=2ohm

R₃=1ohm

Potential (V)=12 V

R_net=R₁||R₂||R₃

$\frac{1}{R_{net}}=\frac{11}{6}$

R_net=$\frac{6}{11}ohm$

$I=\frac{V}{R}=\frac{12}{\frac{6}{11}}=22Amp$
