Ok so I'm really terrible at circuit questions, and am in need of some help. Its a long question so I will just type out he gist of it. Q.A simple type of blinking light circuit (attached diagram) is constructed using a neon lamp. When the voltage is low in RC portion, the lamp does not conduct electricity (not there from electrical point of view). The RC cicuit will charge from the 110V power suply, and when the capacitor reaches 75V the neon lamp will become a good conductor and will immediately discharge the capacitor, energy stored will be given off as a flash of light. After the flash the charging process will start again. a)Determine the flash frequency with the resistance value shown. b) Make a sketch of the voltage across the capacitor in such a circuit, showing several periods. So for part (a) the only equations I could find in my text that I thought might apply are: time constant (T) = RC, therefore T = (2.5 x 10^4)(4 x 10^-6) = 0.1 sec V = Vo(e^-t/RC) 75V = 110V (e^-t/0.1s) ln0.68 = -t/0.1 t = 0.04 sec I'm unsure if this is the answer I'm looking for, that the frequency would be a flash every 0.04 seconds??
