Does the voltage/current rules apply for AC?

In series, current is the same, voltage is shared. In parallel the current is different and the voltage is the same through each component, are these rules still used for alternating current? Or do these rules only apply to DC?

If these rules do not apply for AC, then what rules do apply for AC in terms of voltage and current?

In one word, "yes", it's the same for both AC and DC.

I think they might start to become only good approximations if the frequency is particularly high. But basically the rules are the same.

Yes they will apply in AC resistive circuits.

They wouldn't if you contained reactive elements (capacitors and inductors). These have a 'resistance' (more properly an impedance) that changes with frequency.

The question wasn't about impedences. It was just about current and pd in series and parallel. In those cases the same rules apply.
