Why ac pass by capacitor as it has infinite resistance?
ac passes by repeatedly charging and discharging the capacitor. when you study ac circuit analysis, you will find out about impedance and reactance, which will allow you to compute how ac behaves in capacitors and inductors.
Can you charge inductor with dc voltage or ac voltage?
Inductors are low pass devices, they conduct most easily at low frequencies. DC is the limiting case for low frequency AC: i.e. DC is the lowest possible AC frequency, zero Hz and thus conducts best through an inductor. Capacitors are high pass devices, they conduct most easily at high frequencies. Infinite frequency AC is the limiting case for high frequency AC. Infinity Hz would conduct best through a capacitor.
Am transmitter working principle?
even a single wire can tansmitam signal in which ac signal pass through it
What will happen if you pass ac current passes through a inductor?
magnetic flux will be induced its use to rotate the shaft or given some force
How can you block ac current?
You can block AC current by using a filter with a pass-band that is outside the frequency of the AC current.
Why you using DC power supply for capacitor?
Because it does not allow ac to pass through it...
Why don't capacitors allow DC current to pass?
A capacitor allows AC (to pass through) because capacitors resist a change in voltage.. The capacitor need change resist in Input signal
Can ac pass through capacitor?
AC can pass through a capacitor. The higher the frequency of AC the lower the reactance (like resistance). The current and applied voltage are 90 degrees out of phase the current leading the voltage by this amount.
What is ac ground?
If a circuit is grounded through a capacitor it is referred to as AC ground because ac signal can pass through the capacitor DC level is blocked
Does inductor allow ac to pass through it?
Yes, with some difficulty. You can think of an inductor as a kind of "AC resistor"in a way. The higher the frequency of the AC, the more difficulty it has passingthrough the inductor.If you apply AC voltage across an inductor, whereV = voltage of the ACf = frequency of the ACL = inductance of the inductor,then the AC current through the inductor isI = V/2 pi f L
If an inductor and a switch are connected in parallel through which the current will flow in an AC circuit?
A:The inductor does not allow ac signal to pass through. It blocks ac and passes dc. If the switch is open, then the ac signal wont pass. If the switch is closed, then the ac signal will pass through the switch.AnswerIt is incorrect to say that an inductor 'does not allow' the passage of an alternating current. An a.c. current will pass through an inductor, although the inductor will limit the value of that current due to the inductor's inductive reactance. Inductive reactance, which is expressed in ohms, is directly-proportional to the inductance of the inductor and to the frequency of the supply. The value of the current is determined by dividing the supply voltage by the inductive reactance of the inductor.If the switch is connected in parallel with the inductor, then closing the switch will apply a direct short circuit across the inductor, and the resulting short-circuit current will cause the circuit's protective device (fuse or circuit breaker) to operate.

ac passes by repeatedly charging and discharging the capacitor. when you study ac circuit analysis, you will find out about impedance and reactance, which will allow you to compute how ac behaves in capacitors and inductors.
When capacitor is having an insulation how is it allowing ac current?
Capacitor does not allow any current through it.By the changing of electric field across the plates it is usually assumed that capacitor allow ac through it.Is it???
Why is computer internal components designed to use DC?
Transistors are the main working computer components. They either allow electricity to pass through or not pass through. They are either on or off. To work, they must allow electricity to go only one way. Sometimes transistors are attached to an AC circuit. Still they only let DC electricity come out. They are either on or off and only allow electricity to go one way.

How does a capacitor allow ac?
A capacitor allows AC (to pass through) because capacitors resist a change in voltage. The equation of a capacitor is ... dv/dt = i/c ... meaning that the rate of change of voltage in volts per second is equal to current in amperes divided by capacitance in farads. The simplified explanation (using more words) is that, when a DC voltage is applied to a capacitor, it ultimately charges to that DC voltage and, at equilibirum, presents a large impedance, but when an AC voltage or step change is applied to a capacitor, it initially presents a low impedance, allowing the AC or step to pass through. If you have an AC signal riding on top of DC, the capacitor will stabilize to an output DC offset of zero while passing the AC. This is useful, for instance, when coupling an AC signal to the input of a transistor amplifier, while allowing the base bias circuit to keep the transistor in its intended bias state, while at the same time allowing the AC signal to pass through into the transistor and be amplified.
