Question

ohmmeter is used for measure- (a) current (b) potential difference (c)resistance (d)all of these​

Answer 1

Answer :- (c) resistance

----------------------------------------

Extra information :-

Resistance is measured in Ohms.

Resistance is the opposition to the flow of electric current.

We can find resistance in a circuit with the following formula :

      R = V/I

-------------------------------------------------------

Current (I) is measured in Ammeter.

SI unit of Current is Ampere.

-------------------------------------------------------

Potential difference (V) is the amount of work done for bringing unit charge from infinite to a reference point.

It is measured in Voltmeter.

Answer 2

Q.

Q. Ohmmeter is used for measure →

a) Current

b) Potential difference

c) Resistance

d) All of these

Answer :-

Resistance(option →C)

Ohmmeter :- It is a device which is used to measure the resistance of a circuit.Or ,an electrical appliances.

Resistance :- It is a physical quantity or property to which it resist the flow of an electric current through it is known as resistance.

And the appliances which offers resistance is called resistors.

• It's SI unit is ohm Kept in honor of George Simon ohm.

The relationship between resistance, current and voltage is given by ohm's law :-

$\boxed{\sf{ V = I. R}}$

where I is current

V is potential difference.

R is resistance.
