6 FAQs about [Ammeter external battery internal resistance]

How to determine the internal resistance of an ammeter?

There is this lab procedure to determine the internal resistance of an ammeter which differs from the usual process. In this new procedure, we connect a voltage supply in series with a resistor of some known value and an analog ammeter (top image). We increase the voltage until the ammeter reads 30mA and then turn off the supply.

What is 'internal resistance' in a battery meter?

Load current flows from the battery (under test) through the meter leads en route to the load resistance (inside the meter) so the value of ‘internal resistance’ obtained will be the sum of lead resistance and battery internal resistance.

How to measure internal resistance of a battery?

XPERIMENT 1: DETERMINE THE INTERNAL RESISTANCE OF A BATTERY. The emf of the battery is measured with the voltmeter connected in parallel with the battery. All the switches should be open. The second switch is closed and the readings are taken again. The third switch is now closed and the readings taken again.

How does a learner determine the internal resistance of a battery?

Learners do an experiment to determine the internal resistance of a battery. They use the following circuit in which a variable resistor Q is used to adjust the total resistance of the circuit. They set up the variable resistor on various resistances and then measure the voltage (potential difference) and the current through the circuit.

Does the current range of a Digital ammeter increase load resistance?

The Current range of a digital ammeter has some low, non-zero, internal resistance, which would add to your effective load resistance. Has this been taken into account?

Can a ohmmeter measure the internal resistance of a battery?

The internal resistance of a battery cannot be measured with a simple ohmmeter. The measurement requires a special device or voltmeter with a known load. Overall, the internal resistance of a battery is an important and useful characteristic.
