Volt ampere meters, also known as VA meters, are instruments used to measure the power in an electrical circuit. In direct current (DC) circuits, VA and watts (W) are equal, while in alternating current (AC) circuits, VA represents apparent power, which can differ from true power represented in watts. VA meters can measure a wide range of current values, and they come in two types: voltmeters and ammeters. A voltmeter is connected in parallel with the circuit to be measured, while an ammeter is connected in series with the circuit to be measured. An ideal voltmeter will have infinite resistance, while an ideal ammeter will have zero resistance so as not to disturb the circuit. The symbol for an ammeter in circuit diagrams is a circle with a capital A
