If resistance increases what happens to voltage
Voltage is unable to pass more current.
If resistance is kept on increasing at a certain level no current would pass.
Relationship between voltage and current
It seems you are beginning to study about electricity, an enjoyable and interesting subject.
Most of the time electric flow is compared with the flow of water for easy understanding.
,If we consider water flow, it happens due to a pressure difference (say between the water pressure at the tap and the atmospheric pressure in the surroundings.
As the pressure at the tap is higher, the water flows outward.
Now the amount of water flowing out depends on two factors: 1.
How high the water tank is and 2.
The amount of u201cresistanceu201d exerted by the pipes against the flow of water.
,If the tank is higher, the pressure at tap is more and more water flows out.
,If the pipe is larger, the u2018resistanceu2019 is less and more water will flow.
,Flow of electricity, though not visible to us acts in a similar manner.
Main difference from a water u201ccircuitu201d is that an electrical u201ccircuitu201d must be u201ccompleteu201d or u201cclosedu201d in order to make an electric u201ccurrentu201d flow.
This means that there is a complete path for electricity to flow out from a source (say the + terminal of a battery) go through various wires and any u201cload/su201d (say a lamp) and return to the other terminal of the source (say the - terminal of the battery),The source (say battery) exerts a u201cpressureu201d to drive electricity from the + terminal to the - terminal through an external u201ccircuitu201d (that is a conducting path provided by wires, lamps etc.
connected to form a path from + to -) Actually this is a u201cpressure differenceu201d between the + and - terminals.
We say there is a u201cpotential differenceu201d between the terminals.
Sometimes this potential difference is called the u201cvoltageu201d of the battery.
,Like in our water circuit, the wires and loads in the electrical circuit also exert a resistance to the flow of current.
The amount of resistance depends on the cross-section and length of the wires, material of the wires etc.
If the Voltage is higher, a higher current will flow.
The current is proportional to voltage.
At the same time, the current decreases with higher resistances.
u201cinversely proportional),Therefore, we get the famous Ohmu2019s law which says,I=V/R where V is voltage, R is resistance and I is the current.
,This formula can be written as V=IR and R=V/I as well.
,Welcome to the wonderful world of electricity.
