Question

define ohms law give it's experimental verification​

Answer 1

Explanation:

Ohm's Law - law

According to Ohm's Law, the current flowing in a conductor is directly proportional to the potential difference across its ends provided the physical conditions and temperature of conductor remains constant. I∝V. V=IR.

VERIFYING OHM'S LAW - EXAMPLE

Let resistance used for verification be R. Make a circuit of R, voltmeter and ammeter measuring voltage and current through R, rheostat (variable resistor), and a cell. Connect the components properly. Note down values of voltage and current shown by voltmeter and ammeter. Repeat the above for different values of Rheostat. Record data in a tabular format and calculate

I

V

for each case. Its should be approximately same. Plot V v/s I on a graph paper. A straight line is obtained whose slope equals resistance.
