This is part of a coilgun project I am working on.
So i have an SPST relay rated at 2A, which can be switched by a signal from a 9v battery. The 'higher current' it will be taking is from a photoflash capacitor of capacitance 80uF, rated at 330v.
My question is, provided the capacitor discharges in 4.4ms (from my calculations) will it blow the relay?
I am confused because there are two ways of looking at it:
1) I've calculated that if this discharge continued for one second (which is what current measures - coulombs per second) the capacitor will discharge 6 Amps through the relay, thereby blowing it.
2) HOWEVER, given it can only hold 2.64x10^-2 coulombs and is (for all calculations) fully discharged after 4.4ms, in the full second after it begins discharging the current which has passed through the relay is only 2.64x10^-2 Amps.
So which is correct??
Thanks
