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.

When does a capacitor act as a resistor of infinite resistance?
When the frequency is zero(i.e when dc power is supplied), capacitor is open is treated as open circuit having infinite resistance.
How far can you run 12 AWG wire with 20 amps?
Typically you don't want more than a 10% drop in voltage. If it were a 120 VAC circuit that would be a drop of 12 volts. At 20 Amps that is a resistance of .6 ohms. That is about 380 feet. Allowing for a 10% drop in voltage would allow you to run 20 amps on 12 gauge copper to 151 feet. Also, the NEC suggests, but does not require, that voltage drop be limited to 3% on branch circuits. In the field this is treated by most electricians as an absolute requirement, not a suggestion. This allows you to run a 20 amp load to only 45 feet on 12 gauge wire. Notice that voltage drop is calculated based on connected load, not the rating of the circuit. A 20 amp load would be connected to a 25 amp or 30 amp circuit, requiring larger wire and allowing for longer distance. In a home a 30 amp circuit would most likely be 240v and would require #10 gauge conductors. Using these numbers to calculate a 3% voltage drop allows you to run this circuit 145 feet. At 120v on #10 gauge wire a 20 amp load can be run just over 72 feet.
What is treated earth pit?
A treated earth pit is an earth pit made according to the IS and has dis-connectible flanged connection to the earthing mat. This earth pit is used for measuring individual earth pit resistances.
What gauge ground wire should you use for grounding rod for 200 amp service?
Answer for USA, Canada and countries running a 60 Hz supply service.Standard ground rod is 5/8th inch diameter and 8 feet long and the conductor connected to it is bare #6 AWG copper. Where I live we are required 2 rods, and NEC requires them to be placed a MINIMUM of 6 feet apart. These rods are treated in the NEC as SUPPLEMENTAL to a water line ground.As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
What does E stand for in C45E?
In the designation C45E, the "E" stands for "enhanced." This indicates that the steel has been treated or modified to improve its mechanical properties, such as strength and hardness, compared to the standard C45 grade. C45E is commonly used in engineering applications where higher performance is required.
Why capacitor behave as open circuit against alternating current?
Capacitors store electrical charge. Imagine we have a capacitor. At time 0 seconds we connect a DC voltage across the capacitor - immediately as the voltage is connected the capacitor is at 0 volts and the maximum current (relative to the circuit resistance) flows. At this extreme the capacitor can be treated as a short circuit, so for high frequency AC volts we should treat a capacitor as being a short circuit. As time passes the current in the circuit will go down and the voltage of the capacitor will go up - this is because as the capacitor gains more charge it gains more voltage, lowering the voltage across any resistance in the circuit consequently lowering the current in the circuit. When the capacitor is virtually full no current will flow at all and the voltage across the capacitor will equal the DC source voltage. At this extreme the capacitor can be treated as an open circuit, so for low frequency AC (allowing the capacitor to fill up before the current alternates) we can treat the capacitor as being an open circuit. Technically, it is not an open/closed circuit when it comes to AC because the capacitance will results in a signal lag or lead. However, if the frequency is low/high enough the lag/lead is often negligable.
Are upper case letter equivalent to lowercase?
Uppercase letters are not equivalent to lowercase letters in terms of ASCII values and many programming contexts, where they are treated as distinct characters. For example, 'A' and 'a' have different values and are considered different characters. However, in some situations, such as case-insensitive comparisons or certain search functionalities, they can be treated as equivalent.
What is Grounding and shielding in electronics instrument?
in an electric circuit, it is treated as a reference from which other voltages can be measured. also it acts as a common return path of electric current leakages
When does a capacitor act as a resistor of infinite resistance?
When the frequency is zero(i.e when dc power is supplied), capacitor is open is treated as open circuit having infinite resistance.

Wireless microphone to transmit audio to audio amplifier how?
A wireless microphone transmits audio using a built-in radio transmitter. The receiver, connected to your audio amplifier, captures the signal. Connect the receiver’s output to the amplifier input with a cable. Ensure both devices are on the same frequency for clear sound.
How are movement disorders treated?
Physical and occupational therapy may help make up for lost control and strength. Drug therapy can help compensate for some imbalances of the basal ganglionic circuit
