Resistor 10 ohm 20W

The Resistor 10 ohm 20W is a high-power fixed resistor with a resistance of 10 Ω and a power rating of 20 W. It is made for circuits where an ordinary small resistor would burn out, such as dummy loads for testing power supplies and batteries, limiting inrush current, and safely discharging large capacitors.

Resistor 10 ohm 20W Specifications

• Resistance: 10 Ω
• Power rating: 20 W
• Maximum current at full rating: about 1.4 A (I = √(P ÷ R))
• Maximum voltage at full rating: about 14 V across the resistor (V = √(P × R))
• Polarity: none

Resistor 10 ohm 20W Applications

• Dummy loads for testing power supplies, chargers and batteries
• Inrush and current limiting in power circuits
• Discharging capacitors in power supplies and inverters
• Load and brake resistors for small motors
• Electronics labs and repair benches

What's in the Box

• 1 × 10 Ω 20 W resistor

Tip: At high power the resistor gets very hot, so mount it in free air away from wires and plastic parts and do not touch it while in use. For continuous use, keep the load to about half the rating, under 10 W, for a longer life.
