Rheostats

Rheostats, also called variable resistors, are versatile components that increase or decrease the resistance to control the current in an electrical circuit. These resistors can handle higher currents and are specifically used to regulate the current flow. A rheostat differs from potentiometers, which are typically used for voltage division in low-current circuits. Rheostats integrate a resistive element and a sliding or rotating contact to select a specific resistance value within the device’s range. Their adjustable resistance levels make them ideal for use in a variety of devices and applications, like dimming lights, controlling motor speeds, and tuning electrical devices. 

Why Buy Rheostats?

Purchasing a rheostat offers unparalleled benefits. Their precise control, dynamic adjustments, flexibility, ease of installation, durability, and adaptability in circuits are among the notable benefits. Additionally, investing in variable resistors improves overall system performance and efficiency across different scenarios.

We offer a comprehensive selection of high-quality rheostats, each tailored to specific operational needs. Our collection includes:

• Rotary Rheostats: A rotary rheostat is characterised by a rotating knob or dial that controls the position of the sliding contact. Its robust design ensures durability and precise resistance variation across various settings. 
• Slide Rheostats: Featuring a sliding mechanism, these rheostats allow for linear adjustment of resistance. They are often preferred in applications where visual feedback of the resistance setting is beneficial.
• Linear Rheostats: A linear rheostat is functionally similar to a slide rheostat. These components come with a straight resistive element and a sliding contact. 

Typical Uses of Rheostats:

Rheostats find applications across diverse industries and settings. Some common uses include:

• Motor Speed Control
• Heating Element Control
• Light Dimming
• Laboratory Experiments
• Welding Equipment
• Audio Equipment
