You need to keep track of phase angle in AC, but not in DC.
formula for ac to dc
Choice of electricity defines ac and dc
At high frequency, capacitor can be considered as 1. Short Circuit in AC analysis. 2. Open Circuit in DC analysis. {because Xc= 1/(2*f*pi) where f= supply frequency,pi=3.14} As at high frequencies, in DC analysis, capacitor will be open circuited & can block the DC signal while AC signal is allowed to pass through.. Hence, this capacitor will act as a blocking capacitor for DC supply.
A dc series motor can work on dc and ac because dc motors are totally reversible.
If having DC and AC is required then a PWM pulse width modulator is required to chop the DC to make AC
The AC current oscillates with cycle time to time.
1)ac analysis 2)dc analysis 3)transient analysis
We do study DC Analysis first before AC Analysis for the sake of simplicity, for pedagogic reasons, and also for historic reasons. As useful and as easy to understand as DC is, it serves as a preparatory ladder in studying the more complex behavior of AC. In addition, it is to respect the historical sequence of events since DC sources were first discovered before the AC sources.

Obviously you have not yet begun the AC circuit analysis class. Wait a few quarters.Some components are normally used with DC, some components are normally used with AC, but most components can be used with both DC and AC.
AC analysis is philosophically the same as DC analysis. You use Ohm's law, Kirchoff's voltage and current laws, and Norton and Thevanin equivalents, to progressively analyze each component of a circuit until you know everything about all components. The difference between AC and DC analysis is that you need to consider reactive loads, such as capacitors and inductors, which have a time-varying response to a change in state. This makes analysis more complex, but the basic rules are the same - you just can't use steady state techniques.

A typical AC waveform is symmetrical about a zero crossing point. You can bias the AC with DC such that the AC waveform is symmetrical about the DC voltage.

The difference AC and DC grounding is that AC is alternate current and DC is direct current. Grounding for both AC and DC is the same.
