Is voltage divided into a series circuit?

Answer 1

I think this means "is the voltage applied to a set of impedances (resistors, inductances, capacitors, or individual networks of these) all connected in series, divided up between them?". A series circuit is a set of impedances connected so that the same current flows through each component in turn. The voltage across each component is the impedance of that component multiplied by that same current, and the total of these voltages adds up to the applied voltage. So the answer is "yes". Notice that the individual items of the series, could be more complicated than a simple resistor, etc. but could be a local parallel unit of, say, a parallel combination of a resistor and a capacitor, and in that case it is the impedance of that local item which applies.
