WebTo calculate internal resistance, we use a potentiometer to first calculate the voltage across the battery, with no current through it. Then we attach a resistor in parallel to the battery and recalculate the voltage across it. Since the current flows, this time the balancing length is smaller. Using the battery equation, we calculate the ... WebPotentiometer is an accurate instruments used to compare emf's of a cells,Potential difference between two points of the electric wire Potentiometer is based on the principle that potential drop across any portion of the wire of uniform cross-sectional is proportional to the length of that portion of the wire when a constant current flows through the wire
