Question

What device is used to measure voltage current and resistant?

Answer 1

Answer:

multimeter

Explanation:

A multimeter or a multitester, also known as a VOM (volt-ohm-milliammeter), is an electronic measuring instrument that combines several measurement functions in one unit. A typical multimeter can measure voltage, current, and resistance. Analog multimeters use a microammeter with a moving pointer to display readings.

Answer 2

Answer:

The device that is used to measure Voltage , current and resistance is known as a Multimeter.

Multimeter

• Multimeter is the device that is used in measuring multiple quantities like voltage,current,resistance.

• It is used mainly as a substitute for voltmeter.

More Informations :-

Current

• Electrical current is the amount of charge(electrons) moving through a conductor at a given time.

• It is represented by letter I .

• SI unit of current is Ampere (A).

• It is measured by ammeter.

Voltage

• Potential difference or voltage is the ammount of work done to move unit charge from one point to another.

• It is represented by the letter V.

• SI unit of voltage is Volts(V).

• It is measured by voltmeter.

Resistance

• Resistance is the property of a material to oppose the flow of current through them.

• It is represented by the letter R.

• SI unit is Ω(ohm).

Relation Between voltage , current and resistance

• Relation between voltage , current and resistance is given by the Ohms Law.

• Ohm’s law states that the voltage across a conductor is directly proportional to the current flowing through it, provided all physical conditions and temperature, remain constant.

• Equation of Ohms law is V = IR.(Where V is voltage , I is current and R is resistance).
