Details description

Potentiometer

A Potentiometer is a precision instrument used in physics and electrical experiments to measure electromotive force (emf), compare emfs of cells, or verify Ohm’s Law and Kirchhoff’s laws. It provides more accurate measurements than a voltmeter because it draws no current from the source during comparison.

🧪 Key Features:

  • Type: Typically 1-meter or 10-meter wire type (slide wire or helical type)

  • Material: High-resistance constantan or manganin wire mounted on a wooden or metal base

  • Scale: Marked in centimeters or millimeters along the length of the wire

  • Terminals: Brass binding posts for secure electrical connections

  • Accuracy: High precision, no power loss during emf measurement

📚 Applications:

  • Comparison of emf of two cells

  • Determining internal resistance of a cell

  • Verification of Ohm’s Law and Kirchhoff’s Second Law

  • Used in CBSE/ICSE/State board physics practicals, B.Sc., and engineering physics labs

  • Ideal for studying potential gradient and precision circuit balancing
