How to Perform Ohm’s Law Experiment for Class 10 | Labkafe
How to Perform Ohm’s Law Experiment Objective: Study the dependence of potential difference (V) across a resistor on the current (I) passing through it and determine its resistance. (Ohm’s Law) One of the most common tasks you can face in the 10th-grade physics or science laboratory is to perform the Ohm’s Law Experiment. It is common…

Working Principle of a Microscope | Labkafe
A compound microscope is virtually recognizable anywhere, with its symbolic curved arm, heavy flat base, and delicate lens-bearing tubes stacked on top. We see it in almost every school or laboratory on earth that needs to deal with tiny things. But how does it work? In this article, we will explain the working principle of…

Parts of a Microscope | Microscope Parts and Functions | Labkafe
To know how to operate a thing, you need to intimately know the various operable parts of that thing. So, here are the standard compound microscope parts; we advise you to read this carefully and understand. Structural Components These parts are what hold up everything else of a device. They are the only sturdy parts…

How to use Vernier Caliper to find out least count and measure diameter of Spherical body and Beaker | Labkafe
Aim:To measure (a) diameter of a small spherical/cylindrical body and (b) to measure internal diameter and depth of a given beaker/calorimeter using Vernier Callipers and (c) hence find its volume Apparatus: Theory: A Vernier Calliper has two scales–one main scale and a Vernier scale. Vernier Scale slides along the main scale. The main scale and…

Beam Balance: Physics Experiment Class 11 to determine mass of two different objects | Physical Balance
Aim: To determine the mass of two different objects using a beam balance. Apparatus: Theory : A physical balance or Beam Balance is a weighing instrument that helps in measuring the weight (or gravitational mass) of an object by making use of the principle of moments. It consists of a metal beam B with a…
