Potentiometers are highly accurate because they use the null balance method. This method involves adjusting a known voltage until it exactly balances the unknown voltage, resulting in zero current flow through the galvanometer. At this null point, no current is drawn from the source of the unknown voltage, which eliminates errors caused by the internal resistance of the source, leading to very precise measurements. The correct option is: Use null balance method Send me the next one 📸
