"When the capacitor is charged with 1.21GW of energy"
Yes, thats the level of technical know-how Jaycar normally exhibit. I normally fear going to Jaycar for the following reasons
(1) The staff generally exhibit very poor personal hygiene and smell bad
(2) they always ask what i want something for. ( Seriously, do you really want to know )
(3) They are experts on everything, but only really know how to use the EFTPos terminal
How do you charge anything with Watts of energy??
