Question

state ohms law and explain the activity to prove it​

Answer 1

Answer:

State Ohm's law. (b) Describe an experiment to verify this law. (a)The potential difference across the ends of a given metallic wire in an electric circuit is directly proportional to the current flowing through it, provided its temperature remains the same. This is called Ohm's law.

Answer 2

Answer:

Ohm's law states that the voltage V across a conductor of resistance R is proportional to the current I passing through the resistor (see circuit below). ... I = V / R and R = V / I. The units are in Volts (V) for the voltage V, Amperes (A) for the current I and Ohms (Ω) for the resistance of R.

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.
