| CIRCUIT MEASURING DEVICES - VOLTMETERS | ||
Voltmeters are used to measure voltage. Unlike the ammeter, they are always connected in parallel with the circuit element being measured. The reason the voltmeter is placed in parallel is to measure the voltage drop across a component. The device itself must draw as little current from the circuit as possible to prevent the meter from altering the very circuit it’s trying to measure. Voltmeter sensitivity is expressed in ohms per volt. |
