Can you measure the internal resistance of dry cell using multimeter?

∙ 10y ago
Well, you do use a multimeter to measure it, but not directly. You need
at least one other thing besides the multimeter and the dry cell. Here's
a simple way to do it:
-- Take a resistor. With the meter set to measure resistance,
measure the resistor's value. Call that 'R'.
-- With the meter set to measure voltage, measure the voltage
of the dry cell. Call it 'V1'.
-- Connect the resistor across the dry cell. Measure the dry cell's
voltage again. Call it 'V2 ' this time . V2 will be less than V1 .
The internal resistance of the dry cell is
R times (V1 - V2) / V2

∙ 10y agono, not directly. internal resistance of a voltage (or current) source can only be calculated by connecting the source to a known load and measuring (which can be done with a multimeter) the voltage across (or current through) that load. the difference from ideal determines internal resistance.

How can you measure internal resistance of car battery?
You measure it indirectly using a known load resistance and measuring supplied current. Loading of the ammeter should be known as well, and the load resistance should be made relatively small to get accurate results.
What will be the resistance of a 10kohm resistor when measured using the multimeter with the terminals reversed?
Approximately 10,000 ohms.
How do you measure the resistance in a parallel circuit?
You have to measure the voltage, and the current. The resistance is then calculated by using Ohm's Law.
Why is multimeter not used for insulation testing instead of a megger?
No, you cannot use a multimeter in place of a megger. The megger is used to measure insulation resistance, which could be hundreds of megohms or so. In order to do that, you need a high voltage so as to develop the current needed to sense the resistance. Using an ordinary multimeter would not work as the applied voltage is not high enough, causing the sensed current to be too small to detect.
How do you measure armature resistance practically?
by using measuring meter
How do you measure the resistance of a motor?
we can measure the resistance of the motor by using voltmeter ammeter method of by directly using a multimeter across the armature terminals of the motor in voltmeter ammeter method we should use a less value of dc voltage to find the resistance
How do you measure life in a battery?
by using a multimeter.
How do you determine the emf and internal resistance of a cell?
You can measure the emf of a cell by using a voltmeter, as this draws current from a cell. You can use the voltage, the emf, and the load resistance to determine the internal resistance of the cell.
What is the common use for a multimeter?
A multimeter is used to measure various properties of electricity. The "multi" refers to it multiple functions which can range from volt meter, current meter, resistance meter. The most common use would depend on the users preference to what is needed and measured most frequently.
How do you test the cyp 98 Honda civic ex?
Using a multimeter, measure the resistance across the yellow wire and ground. It should be between 300 and 700 ohms.
Can you calculate the resistance of a component using a meter and a resistor?
yes you can! you can use a multimeter and a resistor.
How do you measure a resistor using multimeter?
a multimeter probably has a Ohm meter as well. If yes, use it and make sure you have the correct scale adjusted. If there is no Ohm meter you should calculate the resistance using Ohms Law. So if you use your multimeter as an Amp meter (in series with the unknown resistor) and you apply a know voltage across you should be able to calculate the resistance by dividing the voltage you applied by the current you meassured (R=v/I) ANSWER: 1 make sure ther is no external power connected 2 short the leads together and adjust for zero reading on the meter. This step is necessary to eliminate the internal battery drifting with time. Unlike voltage and amps reading the scaling of the meter is not important to begin with since a peg meter or a overflow will not destroy the meter immediately but do change the scale to get maximum deflection or digital display.That it

You measure it indirectly using a known load resistance and measuring supplied current. Loading of the ammeter should be known as well, and the load resistance should be made relatively small to get accurate results.
When using Multimeter?
mainly 3 measurement, 1st Voltage, 2nd, Current, 3rd, resistance
What will be the resistance of a 10kohm resistor when measured using the multimeter with the terminals reversed?
Approximately 10,000 ohms.
Why could the total resistance of the circuit vary when measuring resistance using a multimeter?
Residence of one component varies overtime and from component to component.
Why does resistance value measured using multimeter differ from one decoded using colour band?
Resistors have tolerance. So does the multimeter. Standard resistors range from 20% (no fourth band), to 10% (fourth band silver), to 5% (fourth band gold). Resistors will not normally measure exactly what you expect, and proper circuit design must take this into account.The multimeter may not be calibrated correctly.
