ohm's law=the potential difference across a current carrying conductor is directly proportional to the current flowing through it but the temperature should be constant.
it also gives us formula for resistance
R=V/I
in a circuit when you keep increasing the number of cells,the potential difference increases along with current but resistance remains constant.you can draw a graph from observation and can even find resistance from slope.
hope this helps!!!

Hi friend the answer is
OHM'S LAW:
⭐At a constant temperature, the electric current in a conductor is directly proportional to the potential difference (v) between it's end at a constant temperature(.T).
❇Set up a circuit it should consist of nichrome wire AB of length 0.5 metres ,an voltmeter and four cells of 1.5 volts each.
❇First use only one cell as the source in the circuit.
❇Note reading in the ammeter (I),for the current and reading of the voltmeter (v) for potential difference across the nichrome wire AB in the circuit.
❇Repeat the above steps using two cells three cells and then four cells in the circuit separately.
❇Calculate the ratio of V to I for each pair of potential difference (V) and current (I).
❇From the above calculations it is observed that the current (I) is proportional to the potential difference (V).
❇The slope of the lines gives the value of the resistance (R).This relationship, between potential difference and current is known as ohm's law.
