What is the relation between internal resistance and load resistance when current is constant in the circute?
The total resistance of a circuit is the sum of the supply's internal resistance and its load resistance, because they are in series with each other. This is true regardless of the magnitude of, or the variation in, the current.
Why a cell has internal resistance?
due to the electrolyte present between the two electodes of the cell
What are mathematical relationship between resistance and specificconductivity constant?
Cell constant(C) = Resistance(R) X Specific Conductivity(K)
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
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.
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.
Is internal resistance of a cell a defect or not?
no internal resistance of a cell cannot be considered to b as a defect because the resistance is so small as compared to the output we get from a cell this ristance can be neglected..
Why does a mercury cell give constant voltage throughout its life?
A mercury cell maintains a constant voltage throughout its life because it has a relatively constant internal resistance, which helps to stabilize the voltage output. The chemistry of the cell ensures that the voltage remains consistent as it discharges.
What is the unit of internal resistance of the cell?
it's "ohm".

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 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.
