Question

3. Internal resistance of a battery can be measured by :
Ammeter (b) Galvanometer (c) Voltmeter (a) Potentiometer
​

Answer 1

Answer:

Hye✌️✌️

Here is your answer:-

________

A voltmeter measures the open circuit voltage (OCV) with no load, followed by the second reading with a load; Ohm's law calculates the resistance value (voltage difference divided by current equals resistance).

________

Therefore, the right answer is Voltmeter

Hope it helped☺️☺️

Answer 2

Answer:

Potentiometer

Explanation:

Potentiometer is a device used to measure the internal resistance of a cell, to compare the e.m.f. of two cells and potential difference across a resistor. It consists of a long wire of uniform cross sectional area and of 10 m in length. ... The wires are joined in series by using thick copper strips.
