Question

experiment to verify ohm's law​

Answer 1

Answer:

Verifying Ohm's Law - example

Verifying Ohm's Law - exampleMake 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.

Answer 2

Answer:

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

V/R 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.
