to convert the DC into DC.............
In the circuit where the DC motor is added, it was not specified whether the motor was added in series or in parallel to circuit elements. If it was added in series, it will increase circuit resistance and it will cause circuit current to go down. In parallel, the motor will reduce total circuit resistance, and circuit current will increase.
A short circuit.
Not clear what your question is. First of all, circuits are not classified as DC and AC. Circuits are what they are, and you can apply either AC or DC to any circuit. However, considering a circuit that was designed only for use with DC applied. Still your question is unclear. What is transformer action? "Transformer Action" happens in a transformer.
This is because when you introduce a capacitor, the circuit is no longer a DC circuit. If you're using a multimeter see if there is an AC setting to measure the current.
Capacitance will block DC
dc supply is used for control circuit because dc current is an independent source .
DC has no frequency.
to convert the DC into DC.............
yes definitely you can
No.
Transformers only work with alternating currents. So the answer is Yes, BUT it would have to be a DC Pulsing circuit. using flip flop circuit or a 555 circuit or chop circuit.

as it acts ideally as open circuit for dc
In dc equivalent circuit of an amplifier all capacitors are replaced by open circuit because capacitor block dc. As , Xc=1/2πfC We know that that frequency of dc is zero so Xc will infinite so we replace all capacitors with open circuit.
What supplies a dc motor is not current, but voltage. Current is what flows in the circuit formed by the dc motor and for the charge. That current varies according to the resistance of the circuit.
