Question

what is the value of (a)current through 6ohm Resistor
(b) potential Difference across 12 ohm resistor​

Answer 1

Answer:

a)Current through 6 ohm resistor= (2/3) A

b)Potential difference across 12 ohm= (12/5)V= 2.4V

Explanation:

a) 4= I*6

therefore, I=(4/6)= (2/3)A

b)Equation used throughout the solution is $V=IR$

Voltage is same for the wires in parallel

R (second branch) = 12 + 3 = 15 ohm

V= I( second branch) * R( second branch)

therefore, 4=I( second branch)* 15

I(second branch) =(4/15) A

V(through 12 ohm resistor)= (4/15)*12 = (12/5) V =2.4V
