In this post, we will be going to the basics of setting up the retort stand and pendulum experiment. Most probably, this will be the...

This simple circuit involves a resistance wire on the meter rule and the use of jockey tapping at different length L on the resistance...

The variable resistor (rheostat) is a device to control the size of the current by adjusting the resistance on the variable resistor ....

Refer to the video below for the setting up of the apparatus. Why do you need a variable resistor (rheostat)? Without the variable...

A pin in the beaker of water appears higher than its actual position due to refraction of light. In this experiment, you have to adjust...

Vernier caliper and micrometer screw gauge are used to measure length. Vernier caliper is used in general for measuring length...
