# How to Use a Multimeter to Measure Resistance, Current & Volatge

A multimeter is an electrical tool that can be used to measure the resistance, voltage, and current of a circuit. However, some multi-meters used to measure frequency. Mainly, there are two types of multimeters. One is analog and the other is digital.

Controls and terminals of a Multi-meter are

1. Switch for Function: Select the function (voltmeter, ammeter,ohm-meter) and the range is used for the measurement
2. COM Input Terminal
3. Volt Input Terminal
4. 200 mA Input Terminal
5. 10A Input terminal

## How to use a multimeter to Measure Resistance?

A multimeter can be used to check the resistance of any electronic components.  Turn on the meter and select the resistance to measure resistance measurement. Now, insert two wires in the jacks labeled V-resistance and COM. The multi meter now can be used to measure the resistance of a component connected between these two wires.

## How to use a multimeter for Voltage Measurement?

First of all, remove all the connected wires. Turn ON the meter and select V – for DC voltage or V – mode for AC voltage. Insert a red wire in the jack labeled VΩ and a black wire in the jack labeled COM.

So far as when making voltage measurements, the certain voltmeter is connected in parallel with the circuit components across which voltage is measured.

## How to use a multimeter to Measure Current?

If there are wires already connected then 1st of all, we remove all the connected wires. Likewise, Turn ON the meter but here select A for ammeter mode. Insert a red wire in the jack labeled “A” while the black wire in the jack labeled COM.

So, for current measurements, make certain the ammeter is connected in the series with the circuit components through which current is measured.

Connect the multimeter in series with the circuit for current measurements and in parallel for voltage measurements. Be certain the multimeter is switched to ac before attempting to measure ac circuits. Observe proper dc polarity when measuring dc.
