Please see the picture:
The total voltage should be the superposition of DC and AC, and the superimposed voltage should also be an AC,
Because C1 and R1 are connected in parallel, the voltage across C1 and R1 is also the total voltage.
Is the superimposed AC voltage of the two power supplies, then the current of C1 and R1 is the total voltage divided by
The capacitive reactance of C1 and the resistance of R1, if the current of C1 is equal to the AC voltage divided by the capacitive reactance can also
Understand that the current of resistor R1 should be the total voltage (including AC and DC) divided by the resistance,
Why is there only DC but no AC on resistor R1?

I only say four words directly through each other.

Capacitors pass through and resist straight.

The AC should be used for both, whether it should be understood that the vector sum of the current passing through the resistance through an AC cycle is 0, so it is considered that only DC passes.
