Question

is internal resistance of cell effect the balancing condition of meter bridge?​

Answer 1

$\huge{\underline{\underline{\boxed{\sf{\purple{Answer : }}}}}}$

• No, the balance point is not affected by the internal resistance of the driver cell.
• No, it is necessary that the emf of the driver cell is more than the emf of the cells and hence, the balance point will not be obtained if the emf of the driver cell is 1 V instead of 2 V.
