What is critical speed of dc generator?
the maximum permissible speed above which the generator is likely to damage or may cause circuit to fail.
What is the basic function of chopper circuit?
to convert the DC into DC.............
If you have a DC passing through a circuit will the current decrease when you add a DC motor and if so by how much?
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.
In the simplest of dc circuits where the resistance is zero what kind of circuit is it?
A short circuit.
What is the maximum DC voltage you could expect to obtain from a transformer with an 18V rms secondary using a full rectifier circuit with a filter capacitor?
25.46V assuming output of transformer is pure sinewave.
What is the advantage of full wave capacitor rectifier circuit?
to get maximum dc output
What is critical speed of dc generator?
the maximum permissible speed above which the generator is likely to damage or may cause circuit to fail.
Which circuit element is used to block DC in an electronic circuit?
Capacitance will block DC
Why DC supply is used in control circuit?
dc supply is used for control circuit because dc current is an independent source .
Why use DC circuit when frequecy is zero?
DC has no frequency.
What is the basic function of chopper circuit?
to convert the DC into DC.............
Can you call dc-dc converters as a chopper circuit?
yes definitely you can
If AC is replaced by DC in a fluorescent lamp circuit will the circuit work?
No.
Can a step down transformer increase current in a DC circuit?
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.

In parallel, the motor will reduce total circuit resistance, and circuit current will increase.
Why capacitance is not used in DC circuits?
as it acts ideally as open circuit for dc
Why current is supplied to DC motor?
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.
