Put equal quantities of crushed ice into two identical filter funnels P and Q, Place an immersion heater connected to an ammeter, voltmeter and rheostat in P, making sure it is completely covered with ice. Witryna5. The power rating for a rheostat applies only when the entire resistance is in circuit. The heating only occurs in the bit of wire carrying the current. If only half, or 10% of the wire is in circuit, then cooling only takes place on that half or 10%, and the power rating is proportionally lower.

When placed into an electrical circuit, a rheostat can be used to adjust and control the amount of current flowing around it. They do this by varying the resistance on the circuit, without interrupting the supply of power. Rheostats are one common type of electromechanical variable resistor.
Witryna8 wrz 2024 · Rheostat is generally used in applications where high voltage or current is required such as: Changing the light intensity of a light bulb. An increase in the resistance of the rheostat decreases the flow of electric current, leading to dimming of lights and vice-versa.
