Remember me everyone, I am the one that started this thread and I seem to have started a forum punch up in the process. You are quite right Jim, original question was regarding a simple
circuit using a battery and some resistors, it seems to have gone off in all directions, making me smile this is.
Thank you for the circuit diagram, I am not a scientist, my education if that is what you call it was a short electronics course then books. I have put this circuit together before but I do not think it demonstrates how say the same voltage input can give high or lower amps. Has anyone got one?
By the way from a non scientist, I think Ohms law matters in this question, I am prepared to stand corrected. Are you all having a good Easter? Carry on bickering.
Was it you Studiot who said that I should get hold of a bunch of cheap (on/off) switches and some old fashioned filament light bulbs? I thought that filament light bulbs changed their
resistance (impedance?) according to the voltage that was put through them, in which case would it be useful in my question? Now it is ME who is changing the subject.
