Question

Describe an activity to find the relationship between the potential difference across the two ends of a conductor
and the current flowing through it by including in your answer the following:
(i) diagram of the electric circuit.
(i) an observation table.
(in) a V– graph.

​

Answer 1

Answer:

Answer:

Explanation:

1. set up an electric circuit consisting of a 0.5 m long nichrome wire xy, an ammeter, a voltmeter, and four cells of 1.5 V each.

2. First we connect the one cell to circuit and take the reading of ammeter A and voltmeter V for the potential differences across the wire.

3. Then connect the rest of the cells to the circuit and collect the readings of the ammeter and voltmeter respectively.

4. Plot the graph between V and I . The V-I graph is a straight line pssing through the origin.
