What is a Metre Bridge and How Does It Work?
The Metre Bridge, Its Working, and Its Real Life Use in Physics Labs For hands-on learning in physics, few tools are as iconic — or as pedagogically potent — as the metre bridge. Common in nearly every physics lab on Earth, this simple, yet elegant device allows students and educators to accurately measure unknown resistances while bringing […]
How to Adjust Resistance with a Rheostat
How to Adjust Resistance with a Rheostat Rheostat is a variable resistor. This is essential for Ohm’s Law experiments, as it enables users to change the resistance without breaking the circuit. You use a wiper to slide along a resistive wire to change the resistance, its a circuit. Themeans wiper moves and changes the length of wire in which […]
