Description |
An electrometer is an electrical instrument for measuring electric charge or electrical potential difference in a circuit. This wire meter chemically measured direct current (DC) electricity. Edison's electricity meter (or electrometer for short) used electricity to plate zinc onto electrodes. Edison's company could then calculate how much electricity was being used by weighing the electrodes to see how much zinc had accumulated. |
