Verifying Ohm’s law and measuring resistivity

Equipment

  • Metallic Base, which is mounted on it, set of wires that is different from length and diameter.

  • 2 x digital multi meter.

  • DC power supply.

  • Micrometer.

  • Stick ruler.

  • Connection Cables.

Description

In this experiment, we can study the study the factor which the resistance dependence on it.

The factor are:

The length of the wire.

The cross section area of the wire

The material of the wire.

The temperature but there we neglected it.

Then we can verify the ohm’s law and determine the resistivity of the wire.
