explain ohm's law with the help of circuit diagram
Answers
As a simple explanation, Ohm's law states that the current flowing through a resistor or a ohmic circuit is proportional to the potential difference applied to the circuit.
V ∝ I
V=RI
where R is the resistance.
Now, the question comes that whether all circuits follow this law or not? The answer is 'NO'. Only the linear circuits follow this law. A circuit consisting of diodes, triodes and MOSFET's will not follow this law.
To understand the relationship between Current and Voltage:
Suppose you give a potential difference at the end points of a resistor, now electron after experiencing the potential difference will drift towards the end with higher potential. Now, there is resistance which the electron experiences, and by resistance we mean the barrier which doesn't allow the electron to move to the positive end very easily. The resistance basically, slows down the electron. Now, the question comes, that what will happen if the potential is increased? With increase in potential you see the same resistance, however the drift velocity of the electron increases, and since the drift velocity increases, the electron reaches the other end at a higher rate.
Remember, the above explanation is valid only for ohmic circuits. With non-ohmic circuits, the number of charge carriers can change with the change in potential, and hence doesn't obey the Ohm's law.
