Question

Two resistors are connected in series as shown in the diagram. (i) What is the current through the 5 ohm resistor? (ii) What is the current through R? (iii) What is the value of R? and (iv) What is the value of V?​

Answer 1

Answer:

Correct option is

D

3Ω

 Voltage across 5Ω resistor is V=10V

Current, I=RV=510

⟹I=2A

Since resistance 5Ω and R are in series and hence current through both resistance is same.

Hence current through R is also 2A.

Now for R, potential difference is V=6V and I=2A.

Hence , R=IV=26

⟹R=3Ω

Answer 2

Answer:

i)2A

ii)2A

iii)3 ohms

iv)10v+6v=16v
