    • The curve representing Ohms law is Linear.

    Ohm's law exhibits a linear relationship between the applied voltage and the resulting electric current; the current is proportional to the voltage, so the I–V curve is a straight line through the origin with positive slope.

    Ohm’s law states that the current flowing through a conductor is directly proportional to the potential difference applied across its ends, provided the temperature and other physical conditions remain unchanged. Current is directly proportional to voltage difference through a resistor. That is, if the current doubles, then so does the voltage.
    To make a current flow through a resistance there must be a voltage across that resistance. Ohm's Law shows the relationship between the voltage (V), current (I) and resistance (R)

    I∝V

    ⇒V=IR

    Where R is a constant called resistance of the conductor. The value of this constant depends on the nature, length, area of cross section and temperature of the conductor.

    Here, V= potential difference in volt, I= current in ampere and R=resistance (which is a constant).
