🔍 Rheostat

A Rheostat is a variable resistor used in physics and electrical experiments to control current flow in a circuit without interrupting it. It is essential for experiments involving Ohm’s Law, current-voltage relationships, and resistance control.

🧪 Key Features:

  • Type: Sliding contact (linear) or rotary type

  • Material: High-resistance wire (usually nichrome) wound over a ceramic or metal tube

  • Range: Available in various resistance values like 10Ω, 50Ω, 100Ω, etc.

  • Current Capacity: Typically ranges from 1A to 5A

  • Terminals: Three binding posts (2 for fixed ends, 1 for sliding contact)

📚 Applications:

  • Varying current in Ohm’s Law and circuit experiments

  • Used to adjust resistance and voltage in series circuits

  • Demonstrates current control, power dissipation, and linear resistance behavior

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