Hi All,
Please excuse this simple question, I'm new to electrics/electronics and teaching myself...........
A question about voltage drop.......
When we talk about a voltage drop across something, do we mean the voltage has dropped TO - or voltage has dropped BY.
For example, in a series circuit I have a 9v battery and when I put in a resistor of q ohms and measure the volts it reads 1.5v.
Does that mean there is 7.5v through the resistor or 1.5v?
I think it means the voltage has dropped BY because the series rule is: "total voltage in a series circuit is equal to the sum of the individual voltage drops". But please confirm,
Thanks,
Steve
