Why does potentiometer measure the potential difference more accurate than a voltmeter?

Why terminal potential difference is less than the emf of a cell?
Answer : The terminal potential difference of a cell is less than its electromotive force (EMF) due to the internal resistance of the cell. Here's why: 1. **EMF of the Cell**: The EMF is ... the voltage drop inside the cell, and therefore, the smaller the terminal potential difference compared to the EMF....

Why FET is more stable than BJT?

Why FET is more stable than BJT?
Answer : FETs (Field-Effect Transistors) are generally considered more stable than BJTs (Bipolar Junction Transistors) for several reasons: 1. **No Current Flow Through the Control Terminal**: In ... operation, and have higher input impedance, making them less sensitive to variations in their environment....
