Question

experiment to verify ohms law​

Answer 1

Answer:

plz mark as brainiest

Explanation:

Experiment to verify Ohm's law: Set up a circuit as shown in figure shown, consisting of a nichrome wire XY of length, say 0. ... Note the reading in the ammeter I, for the current and reading of the voltmeter V for the potential difference across the nichrome wire XY in the circuit. Tabulate them in a table.

Verifying Ohm's Law - example

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.

Answer 2

Explanation:

Experiment to verify Ohm's law:

Set up a circuit as shown in figure shown, consisting of a nichrome wire XY of length, say 0.5m, an ammeter, a voltmeter and four cells of 1.5V each. First use only one cell as the source in the circuit. Note the reading in the ammeter I, for the current and reading of the voltmeter V for the potential difference across the nichrome wire XY in the circuit. Tabulate them in a table. Next connect two cells in the circuit and note the respective readings of the ammeter and voltmeter for the values of current through the nichrome wire and potential difference across the nichrome wire. Repeat the above steps using 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. In this experiment, we will find that approximately the same value for

I

V

is obtained in each case. Thus the V–I graph is a straight line that passes through the origin of the graph, as shown in the figure. Thus, V/I is a constant ratio, which verifies Ohm's law.
