Accordingly, what is DCA used to measure?

Different multimeters have different symbols formeasuring direct current (and the corresponding voltage),usually "DCA" and "DCV," or "A" and "V" with a straight barabove or next to them. Alternating current (abbreviated AC) iscurrent that changes direction, usually many times in onesecond.

Likewise, what does v mA mean on a multimeter? The selection knob allows the user to set themultimeter to read different things such as milliamps(mA) of current, voltage (V) and resistance(Ω). Two probes are plugged into two of the ports on thefront of the unit. COM stands for common and is almost alwaysconnected to Ground or '-' of a circuit.

Subsequently, question is, what is DCV electricity?

DCV: This range of settings allows the multimeterto be used as a voltmeter, specifically to measure direct currentvoltages. A voltmeter measures the difference in electricpotential (voltage) across a circuit component. The batteries inyour car and in a flashlight are DC voltagesources.

How do you measure DC voltage with a multimeter?

Set the knob to "20V" in the DC range (the DCVoltage range has a V with a straight line next to it).Multimeters are generally not autoranging. You have to setthe multimeter to a range that it can measure. Forexample, 2V measures voltages up to 2 volts, and 20Vmeasures voltages up to 20 volts.
