A battery of emf 10 v and internal resistane `3 Omega` is connected to a resistor. If the current in the circuit is 0.5 A, what is the resistane of the resistors ? What is the terminal voltage of the battery when the circuit is closed ?

Text Solution

Verified by Experts

`E = I (R+ r ) `
` 10 = 0.5 ( R+ 3 ) `
` R= 17 Omega `
` V = E - Ir = 10 -0.5 xx 3 = 8.5 V `
