Question

V1, V2 and V3 are the potential differences across the 1Ω, 2Ω and 3Ω resistors in the following diagram, and the current is 5A. Which of the following shows the correct values of V1, V2 and V3 measured in volts

Answer 1

Answer:

V1= 5.0, V2= 10.0, V3= 15.0, It means, the current flowing through each resistor is same.

Explanation:  

From the diagram, it is clear that the resistors are connected in series. It means, the current flowing through each resistor is same.

Given:

So, from the Ohm’s law, we get

                     V = IR

Now,  

V1=IR1= 5Α×1Ω= 5V

V2= IR2= 5Α×2Ω=10V

V3=IR3= 15V
