@rajasekhar-

Current is the rate at which electric charge flows past a point in a circuit. In other words, current is the rate of flow of electric charge.
Voltage, also called electromotive force, is the potential difference in charge between two points in an electrical field. In other words, voltage is the "energy per unit charge”.

If the resistance increase then gragually current decerease. So that think logically that whn resistance increase thn load incerase in the wire so rate of current is to be slow.

V is proportional to I means V/I=constant. Again, V=IR or, V/I=R. So if the load R increases and keep the current constant, then V also increases.

Note:

In Practical Applications battery voltage is lowered as load increases.

Or

In Practical Applications battery voltage is lowered as load Resistance decreases .

Both are correct. Hope Understood meaning of Load and Load resistance.

Whats the difference between load and load resistance?

Sharma said:   1 decade ago
When in our home we switch on many heavy electrical devices simultaneously then automatically the tube lights get dim. And that is only due to the dropping of voltage. That's it. :).

Its very simple when we use some energy then automatically battery discharge.

Sindhu jyesta said:   1 decade ago
As load increases current decreases through resistance so that battery (voltage) discharges automatically.

What is different between inductor and capcitor?

Pradeep raj said:   1 decade ago
Inductor it is a bulky component and it is responsible for magnetic field usually units are HenrY.

WHEREAS CAPACITOR is skinny and it is responsible electric field.
