Power Resistor
I intend to build an artificial load using the load resistance on a 12V 5A?
What values in terms of ohms, and how many watts of resistance to use? How to calculate?
need a resistance of 12 ohms / 5 or 2.4 (Act Ohm) you must be 12 or 60 watts x 5 at least you can make a television series or parallel resistance, the calculation of power each better. use more power than expected. For example, 10-24 ohm resistors in parallel, each 6 watts. 100-240 Ohm resistors in parallel, each 0.6 watts Personally, I October 24, 1910 ohms or 20 watts resistance. Wire in parallel. Use heavy gauge wire such as buses and solder each resistor them. Leave a space between the resistors. Of course to use the heavy wire to handle 5 amps. change. The bulbs can be used, but: 1. are highly non-linear, so if you configure it for 5 amps at 12 volts, you will NOT 2.5 amps at 6 volts. 2. They are not accurate, you to do a lot of trial and error to get the right load. 3. change over time and burn. 4. are fragile.
