# How do I make a high watt resistor?

## How do I make a high watt resistor?

Yes, you can make a high power resistor from multiple low power ones. The simplest way to do this is to put them all either in series or all in parallel. With N resistors in series, make each 1/N the total desired resistance. Similarly, with N resistors in parallel, make each N times the desired resistance.

## What size is a 1/2 watt resistor?

A common ½W resistor measures about 9.2mm across, while a smaller ¼W resistor is about 6.3mm long. A half-watt (½W) resistor (above) sized up to a quarter-watt (¼W). Surface-mount resistors are usually tiny black rectangles, terminated on either side with even smaller, shiny, silver, conductive edges.

How big is a 2 watt resistor?

Resistors – 2 Watt, Metal Oxide, Power

Body Length 15.0 mm
Item Diameter 5.0 mm
Operating Temperature (TJ) -55°C to 240°C

### What happens if I use a higher watt resistor?

Wattage refers to the maximum that a resistor can dissipate. So subbing a higher wattage for lower is perfectly fine without any changes.

### Can I make my own resistors?

To create a wirewound resistor, one piece of wire would have to serve as the path for the electrical current to flow from one end of the resistor to the other. To create a resistor with a small resistance (or Ohm) value, use a thicker, shorter wire as the path between the two electrical leads.

How many watts resistor do I need?

Generally speaking the larger their physical size the higher its wattage rating. However, it is always better to select a particular size resistor that is capable of dissipating two or more times the calculated power….The Resistor Power Triangle.

Type Power Rating Stability
Wirewound High up to 500 Watts High 1%

## What size of resistor do I need?

We’ll use the following formula to determine the resistor value: Resistor = (Battery Voltage – LED voltage) / desired LED current. For a typical white LED that requires 10mA, powered by 12V the values are: (12-3.4)/. 010=860 ohms. To use several LEDs in parallel, sum the current values.
