EXPERIMENT 11 THE POTENTIOMETER I. THEORY The purpose of this experiment is to measure the electromotive force (emf) and internal resistance of a dry cell. The terminal voltage of a cell is the potential difference between its terminals. The emf of a cell may be defined as the terminal voltage of the cell when not under load, that is,
Measure the Battery Voltage Under Load. Step 3: Measure the battery voltage with a voltmeter and record this as well, as it may differ slightly from a no-load condition. We saw this effect exaggerated in the parallel battery experiment while powering a high-wattage lamp. The battery voltage tends to "sag" or "droop" under load.

When reactions stop after the chemicals are consumed, the battery goes dead. Power of a battery is measured in mAh (mili Ampere per hour) or Ah (Ampere per hour) and indicated on the battery. For example, if a battery is labelled 10Ah, it means the battery can deliver or take 10 ampere load for 1 hour. Or, 2 ampere load for 5 hours.
