 Basic Electrical Measurements

 To measure resistance, voltage and current in various devices ohmmeter, voltmeter and ammeter is used, respectively.

1. Ohmmeter

Resistance is measured in Ohmmeter. It is also available in both analog and digital forms. Measurement unit is Ohm (Ω).

2. Voltmeter

A voltmeter is used to measure voltage. The proper name for voltage is 'potential difference', but most people prefer to say voltage! Measurement unit is voltage (V). 

3. Ammeter

An ammeter is used to measure current. It is also referred to as ampere meter. Measurement unit is Ampere (I).  

1 Resistor –Resistance Ohm Ω

2 Current Ampere I

3 Voltage Volt V

4 Capacitor- Capacitance Farad F

5 Inductor-Inductance Henry L

6 Power Watt W
