Question

resistance can be measured with the help of mcq​

Answer 1

$Micro-ohmmeters$

An ohmmeter is an electrical instrument that measures electrical resistance (the opposition offered by a substance to the flow of electric current) . Micro-ohmmeters (microhmmeter or micro ohmmeter) make low resistance measurements. Megohmmeters (also a trademarked device Megger) measure large values of resistance.

Answer 2

Explanation:

Resistances can be measured with the help of :-

Device - Quantity to be Measured

Ammeters - current

Voltmeters - Voltage

Wattmeter’s - Power

Ohmmeters and resistance bridges - Resistance

Resistance is measured using an instrument - an analog multimeter or digital multimeter.

Both types of instrument can measure - not only resistance, but also current, voltage, and other thing also - so they can be used in a variety of situation.

Resistance measurement does not - involve measuring the circuit’s resistance value itself.

Resistance is calculated by measuring - the current and voltage - applied to the circuit.

When a current is applied - to the circuit under measurement - the circuit (resistance) exhibits a voltage .

Resistance can be calculated - by measuring the current and voltage - using Ohm’s Law.
