I am studying the schematic for a reactive load box – a device which can be plugged into a guitar amplifier instead of a speaker, on the website http://www.aikenamps.com/index.php/designing-a-reactive-speaker-load-emulator .
The circuits uses a 'bipolar' capacitor – a component i have previously not heard of. I am familiar with parallel-plate capacitors and electrolytic capacitors, and the physics of them both but the mention of a bipolar cap has confused me. There are debates online about creating a cap from two bipolar caps connected head to head, but there doesn't seem to be much on the component itself.
- What is it
- What notable uses does it have?
