🔍 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
