Which components have a high resistance in the dark but low resistance in the light?
A Cadmium Disulphide cell. (aka Cds 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.
Why a cell has internal resistance?
due to the electrolyte present between the two electodes of the cell
Do batteries have resistance?
Yes they do have a resistance. Even though a battery is a voltage source it has some thevenin resistance. Every lead plate and cell of sulfuric acid, will have a small resistance. The thevenin resistance is equivalent or sum of all those resistances.
What are input impedance in a load cell?
The resistance measured across the excitation terminals of the load cell, when the output terminals are open.
Does the sickle cell recessive trait decrease the body's resistance to malaria?

Will putting cell phone into liquid nitrogen to decrease electrical resistance change apps in cell phone?
No. It might damage the phone, though.
This element's resistance to the flow of electricity is greatly affected by the amount of light shining on it?
The element described is a photovoltaic cell, which produces electricity when exposed to light. The electrical resistance of a photovoltaic cell decreases as more light shines on it, allowing it to generate more electricity.
Does the power output of a solar cell vary with ambient temperature?
Yes, the power output of a solar cell typically decreases with increasing temperature. As the temperature rises, the efficiency of the solar cell decreases, leading to a decrease in power output. This is due to the relationship between temperature and the electrical properties of the materials used in the solar cell.
Would a substance that decreases membrane permeability to sodium increase or decrease the generating of a nerve impulse?
A substance that decreases membrane permeability to sodium would decrease the generation of a nerve impulse. This is because sodium ions play a crucial role in depolarizing the membrane and initiating nerve impulses. By reducing sodium influx into the cell, the ability of the neuron to generate an action potential would be diminished.
What happens to a cell ratio of surface area to volume as the cells volume increases more rapidly than its surface are?
The cell's ratio of surface area to volume would decrease. However, this scenario is extremely unlikely.
When water leaves a plant cell the osmotic pressure will increase of decrease?
When water leaves a plant cell, the osmotic pressure inside the cell will increase because there will be a higher concentration of solutes relative to water. This increase in osmotic pressure leads to plasmolysis, where the cell membrane shrinks away from the cell wall.
Would the water potential of a potato cell decrease or increase when it is allowed to dehydrate?
decreases it - no water then no water potential.
When a cell loses water what happens to its size and weight?
When a cell loses water, it undergoes shrinkage, resulting in a decrease in size. This process is known as plasmolysis in plant cells, where the cell membrane pulls away from the cell wall. Consequently, the weight of the cell also decreases due to the loss of water, which is a significant component of its overall mass.
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..
What happens to the surface of the cell as the volume of the cell increases?
As the volume of a cell increases, the surface area of the cell also increases, but at a slower rate. This can lead to a decrease in the surface area-to-volume ratio of the cell. A decreased surface area-to-volume ratio can impact the cell's ability to efficiently exchange materials with its environment, potentially affecting its overall functioning.
