I'm making a new capacitor discharge tool. Asking for suggestions for sizing the discharge resistor.
Mr. Carlson's Lab High Voltage Capacitor Discharge Tool 1 is using 4 of 1kΩ 50W aluminum (mount to heatsink) resistors in series for 4kΩ 200W, so it's big, which is fine.
His Patreon but I don't have a paid subscription for the project details but it looks straightforward. The plastic box with aluminum plate can't get rid of any amount of that heat though.
Wirewound resistors can be overloaded by a factor of 5 for 5sec. and a factor of 10 for brief times. I've never tried say...
