Question

What is the voltage drop across the 3.0 Q for a parallel circuit containing a 12 V potential and three resistors R1= 3 ohms, R2=2 ohms and R3= 1 ohm

Answer 1

Given

Potential (V)=12volt

R₁=3ohm

R₂=2ohm

R₃=1ohm

R_net=R₁||R₂||R₃

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

Current

$I=\frac{V}{R}$

$I=\frac{12}{\frac{6}{11}}$

$I=22Amp$

Voltage drop across all three

resistance are parallel circuit

$V_{T}=V_{1}=V_{2}=V_{3}$

R₂ corresponding voltage drop

V₂=12$volt$
