What else can I help you with?
What are the main difference while applying kirchoffs laws to dc circuits and ac circuits using meter readings?
For DC circuits, an alebraic sum is required. For AC circuits, a phasor sum is required.
What is the opposition of current flow measured in?
The opposition of current flow is measured in ohms. For DC circuits it is resistance and for AC circuits it is impedance.
What is the function of input and output coupling capacitors CC1 and CC2?
We don't know much about the circuit these capacitors are in, but they are coupling capacitors. Coupling capacitors isolate DC between stages or circuits, and they couple AC between those circuits or stages. Only the signal gets in and goes out. The DC the stage operates on is isolated from stage to stage.
Why you use capacitive filters in rectifier circuits?
In any rectifiers circuits the purpose is to get a DC voltage by giving AC voltage as input.by connecting capacitors parallally in the circuit it is possible to get pure DC output.capacitor filter only eliminates the ac quantities remainimg in the output waveforms.so that finally we get pure DC for further aplications in electronics circuits.
Kirchoff's Voltage and Current Laws apply to all ac circuits?
Kirchoff's Voltage and Current Laws apply to all AC circuits as well as DC circuits. Other laws, such as Ohm's law and Norton and Thevanin equivalents apply equally as well. The complicating factor is that, at AC, current and voltage are not usually in phase with each other, unless it is a simple resistive circuit. That makes the math harder, but it does not make it invalid or impossible.
Why is voltage regulation of dc line is better than ac line?
in dc circiuts only resistors are responsible for voltage drop. where as in ac circuits inductances and capacitances are also responsible for voltage drop in addition to that of ressistors
What is the function of an AC transistor in electronic circuits?
An AC transistor in electronic circuits is used to amplify and control the flow of alternating current (AC) signals. It acts as a switch or amplifier to regulate the voltage and current in the circuit, allowing for the manipulation and processing of AC signals for various applications.
What is the function of mylar capacitor?
In electronic circuits a capacitor is used to pass AC and block DC.
What is an AC capacitor and how does it function in electrical circuits?
An AC capacitor is an electronic component that stores and releases electrical energy in alternating current (AC) circuits. It functions by storing charge when voltage is applied across its terminals, and then releasing this stored energy when needed to help regulate voltage levels and filter out noise in the circuit.
How do you solve AC circuits problems?
Use of complex numbers for circuit values (e.g. voltages, currents, reactances) is required to get correct answers for AC. The equations are the same as for DC circuits, but the numbers are complex not real. Also reactances vary with the frequency of the AC signals in the circuit.
What are the main difference while applying kirchoffs laws to dc circuits and ac circuits using meter readings?
For DC circuits, an alebraic sum is required. For AC circuits, a phasor sum is required.
Do you need to put a shunt resistor to connect the ac voltmetr?
Shunt resistors are used with ammeters; voltmeters require series resistors.
What are the answers to njatc ac theory workbook j203swh?
resistors in series
What is the use of capacitor in dc circuits?
It will minimize curent flutuations, it olso helps in AC circuits( in AC I tink it absorbs frequenci emmisions).
How can you fix a heater and AC fan that only work on high?
Resistors control the speed of the AC/Heater fan. These resistors are switched on and off in various combinations to create the different fan speeds. When the resistors burn out your fan will only work on the "HI" setting. The "HI" setting doesn't use any of the resistors and that's why it works. These resistors are near the blower and the blower is beneath the dashboard on the pasenger side. Just have to located resistors now.
What does ac stand for in circuits?
alternating current
Why would the heating-AC fan on a 1994 Dodge Caravan only run on high?
Resistors control the speed of the AC/Heater fan. These resistors are switched on and off in various combinations to create the different fan speeds. When the resistors burn out your fan will only work on the "HI" setting. The "HI" setting doesn't use any of the resistors and that's why it works.
