A capacitor that is suddenly connected to a battery will charge to the battery voltage. The time to do this is dependent on the current capacity of the battery and wiring, and the capacitance of the capacitor. This represents an instantaneous short circuit, which lasts for a (usually) very short time - but damage could be done if there was no resistance.

A charged capacitor that is suddenly disconnected from a battery will hold that voltage. The length of time it will hold is dependent on how much leakage current there is.

Why capacitor is connected in voltage divider emitter bias?

In a voltage divider emitter bias configuration, a capacitor is often connected in parallel with the emitter resistor to stabilize the biasing conditions. This capacitor provides AC coupling, allowing AC signals to pass while blocking DC, which helps maintain a consistent operating point by preventing variations in the emitter voltage due to signal fluctuations. Additionally, it improves the amplifier's frequency response by bypassing the emitter resistor for AC signals, effectively enhancing gain at higher frequencies.


For higher frequency response which type of capacitor is used?

Probably vacuum ac capacitors.

What is RC load?

An RC load refers to a circuit component consisting of a resistor (R) and a capacitor (C) connected in series or parallel. This configuration is commonly used in electronic circuits to filter signals, store energy, or manage timing applications. The combination of resistance and capacitance affects the charging and discharging behavior of the capacitor, influencing the circuit's frequency response and transient behavior. RC loads are fundamental in applications such as low-pass and high-pass filters, timing circuits, and signal processing.


What happens when shunt capacitor is added to the bus which is driven by synchronous motor?

When a shunt capacitor is added to a bus driven by a synchronous motor, it provides reactive power support, improving the voltage stability of the system. This addition helps to offset the reactive power demand of the motor, thereby enhancing the overall power factor and reducing losses. Additionally, it can improve the transient response of the system and allow for better control of voltage levels, ultimately leading to more efficient operation of the synchronous motor and connected loads.

How many time constants does it take to fully charge a capacitor?

If a resistor is connected in series with the capacitor forming an RC circuit, the capacitor will charge up gradually through the resistor until the voltage across the capacitor reaches that of the supply voltage. The time called the transient response, required for this to occur is equivalent to about5 time constantsor5T. This transient response timeT, is measured in terms ofτ= R x C, in seconds, whereRis the value of the resistor in ohms andCis the value of the capacitor in Farads. This then forms the basis of an RC charging circuit were5Tcan also be thought of as"5 x RC".

Why we are differentiating if capacitance is connected to the circuit?

Because the response characteristic of a capacitor is time dependent - it's impedance changes as a function of time. Differentiating will show the speed of this change, just like differentiating a line will give the slope of the line.

How much time constants to charge or discharge a capacitor?

Theoretically, forever, because as the voltage on the capacitor approaches the source voltage, the available current to charge the capacitor approaches zero.In practice, however, it simply depends on what you call "charged".In the simple example of a capacitor being charged from a voltage source in series with a resistance, the voltage is given by ...VT = Vs (1 - e -T/RC)... so, if your definition of "charged" is 99% of VT then T would have to be 5 RC's or 5 time constants.If a resistor is connected in series with the capacitor forming an RC circuit, the capacitor will charge up gradually through the resistor until the voltage across the capacitor reaches that of the supply voltage.

What is the effect of a dielectric material on the electric field of a capacitor?

A dielectric material placed between the plates of a capacitor reduces the electric field strength within the capacitor, increasing its capacitance. This is because the dielectric material polarizes in response to the electric field, creating an opposing electric field that weakens the overall field between the plates.
