A battery of e mf 10 V and internal resistance `3Omega` is connected to a resistor as shown in the figure. If the current in the circuit is 0.5 A . then the resistance of the resistor will be

A

`19 Omega`

B

`17 Omega`

C

`10 Omega`

D

`12 Omega`

Text Solution

Verified by Experts

The correct Answer is:
B
`I = 10/(3 + R) rArr 0.5 = 10/(3 + R) rArr R= 17 Omega`
