I have been reading as much as I can about the basics e.g. Ohms law, I,V,R and P so far and most of the tuition seems to be based on resistor circuits in which in order to calculate current when V and Rtotal are known is merely Ohms law of I=V/R. So I wondered what happens when I put a few basic components into the mix and it seems to change some things and adds to my confusion.
My series circuit in a clockwise direction is a 9V battery, 1N4001 Diode, 120 ohm, red 3mm LED, 120 ohm, red 3mm LED.
The only way that I can see how to calculate the current is to subtract the total of the forward voltage of the diode and the two LEDS from my 9V and divide that by the total resistance.
So if i'm antwhere close to being right this means that although there is a Vdrop across resistors they don't count in this calculation since there are "real" components in the circuit. Is that correct.
Also is there a different /more professional method of calculating current in this instance?
I will pose my parallel circuit question on a different thread.
Many thanks.
