For non-engineering purposes, a harmonic is a predictable repeating undesired waveform. It usually comes from a type of power supply used in modern electronics called a switching power supply.
A harmonic can exist on both AC and DC power. Harmonics can have a seriously detrimental impact on the longevity of electrical devices and systems.
What else can I help you with?
What are smothing reactors?
a smoothing reactor in dc circuits reduces harmonic currents in dc lines.
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.
How can you find the steady state current in RLC series circuit?
-- If the excitation source is AC, then the steady state of the circuit depends on the voltage, frequency, and waveform (harmonic content) of the source. -- If the excitation source is DC, then the steady state current in a series circuit is zero. DC doesn't pass through a capacitor.
What is the direction of DC current flow in a circuit?
In a circuit, DC current flows from the positive terminal of the power source to the negative terminal.
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.
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.
Why capacitance is not used in DC circuits?
as it acts ideally as open circuit for dc
