Define Internal Resistance?
The internal resistance of a device is the resistance in ohms of that device. It is the resistance electrons need to overcome before electricity is said to flow.
What is the value of internal impedance of ideal current source?
internal resistance is always infinite in ideal current source .the internal resistance is in shunt with current source
What is the resistance of that draws a current of 25 amperes from a 1.5volts dry cell?
1. Theoretical AnswerR=1.5/25=0.6 Ohms2. Practical Answer: Dry cells will not be able to deliver 25A as there are two limtationa) Internal Resistance that limits the max current.round couple of Ohms. Max current that it can supply is about 1-2 A.b) Capacity of Dry cells which are typical 700maHr. Even if cell could supply 25A it will only be for 1.7 minutes and then cell will become dead.c) as the cells get drained there is increase in internal resistance which will further reduce the current.
What is a substance that has no internal resistance to flow?
its a liquid
How resistivity effects internal resistance of a cell experiment?
Resistivity effects internal resistance of a cell experiment by not allowing the cell to react. Internal resistance experiments are performed in advancing physics classes.
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.
Why is the internal resistance of a cell not constant?
The internal resistance of a cell is not constant because a cell needs to move and be flexible in order to undergo various osmosis or diffusion processes.
What is the unit of internal resistance of the cell?
it's "ohm".

Why a cell has internal resistance?
due to the electrolyte present between the two electodes of the cell
What causes the internal resistance of a dry cell to increase as time passes by?
The internal resistance of a dry cell can increase over time due to chemical reactions taking place within the cell that can degrade the electrodes and electrolyte. This can lead to the build-up of resistance within the cell, affecting its overall performance and reducing its ability to deliver current effectively. Additionally, factors such as cell aging and discharge cycles can contribute to the increase in internal resistance over time.
How the chief defect of a simple voltaic cell can be removed?
The chief defect of a simple voltaic cell, which is its limited lifespan due to the depletion of reactants and buildup of products, can be mitigated by implementing a more efficient design, such as a rechargeable battery. This can be achieved by using reversible chemical reactions that allow the cell to be recharged by applying an external voltage, restoring the original reactants. Additionally, incorporating advanced materials can improve ion transfer and reduce internal resistance, enhancing overall cell performance and longevity.
Can you measure the internal resistance of dry cell using multimeter?
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
How does internal resistance affect operation of a cell or battery?
It causes the battery's voltage to drop when a current is drawn from it.
What is responsible for lost volts of a cell?
A cell has internal resistance, which means that some of the potential(voltage) it provides is used up just in getting current out of the cell and into the circuit.
What formula to find the emf and internal resistance for cell when given the current and the voltage?
I don't think you can do that, with the information provided.
