PHYSICS PRACTICAL I CARRIED OUT WITH MY STUDENTS ON ELECTRICITY.

Materials needed:

  • connecting wires

  • voltmeter

  • resistance box

  • Key

  • Cell

Connect the circuit as shown above.
When the key is closed, 1 Ohm resistor is removed band the potential difference, V is taken. The students were made to evaluate V inverse and R inverse.

The experiment was repeated for four other values of R which are 3, 5, 7, 9 and in each case V is found. V inverse and R inverse was evaluated.

They were made to plot graph of V inverse against R inverse.

The slope was found and the intercept on the vertical axis was found.
