1 For a parallel plate capacitor which is being charged out What the incorrect statement is?
Energy stored in the capacitor does not enter it through the connecting wire through the space around the wires and plates of capacitor.
What is the purpose of connecting capacitor bank in series with 220 kv feeders?
A: Its purpose is to correct the power factor of the line.
Why yagi uda antenna is used?
Some advantages of the Yagi- Uda Antenna include that this is a widely used design and low cost. The construction also is simple. Some disadvantages are that the receiver of the Yagi-Uda Antenna may have problem receiving signal.
How do you discharge high dc voltage capacitor?
When a capacitor is powered off in an energized circuit, the capacitor still stores a certain amount of electricity. When there are other loads or components in the circuit, they will slowly discharge, or they can be quickly discharged by short-circuiting with small resistors or wires (at low voltage). When the capacitor discharges, the two poles of the capacitor respectively carry a certain amount of charge, and the outside world and the capacitor form a closed loop (generally, the closed loop does not include a power supply). The excess electrons (negative charges) approach the positive electrode of the capacitor to form a current, so that the charges at both ends of the capacitor are neutralized. When the neutralization is completed, the electric field between the two electrodes of the capacitor disappears. However, this is in an ideal situation. The amount of terminal charge is exponentially neutralized towards zero, but not zero. Discharge requirements of capacitors After the capacitor is disconnected from the bus, it must be discharged through a discharge resistor or a special voltage transformer. Discharge should be performed between the lead wires of the capacitor and between the lead wires and the casing. The capacitor can be grounded after the capacitor is discharged. Before working on the capacitor, be sure to conduct a test discharge. This discharge is to place the discharge rod on the terminal of the lead wire of the capacitor for a period of time. Even if both sides of the capacitor device are grounded, in order to prevent residual charge on the capacitor, a test discharge must be performed, and each group of capacitors connected in parallel must be discharged. Special care should be taken when conducting inspection discharge of capacitors removed due to faults. Due to the damaged capacitor, the general grounding device may not function as a ground discharge due to a partial disconnection. If the capacitor device has an interlock device, it should be considered that only after the entire device is grounded, the small door of the capacitor bank protective fence can be opened.

Why you use capacitor before connecting transtitor?
Before connecting to the transistor we use a capacitor becausefor the transistor to amplify we should first apply DC biasing so that we can set an operating point to itso once the transistor is biased DC currents flow in the whole circuitryAll the AC signal source are shorts to the DC currents so we employ capacitor for two reasons1.As capacitor blocks DC and allows AC it is connected for not moving the DC operating point of the transistor and making it fixed since if any small DC part arises in the signal it leads to the change of operating point and our amplification procees gets affected2.To block the already present DC currents in the circuitry for not getting away and making it fixed

How does a capacitor discharge if there is dielectric material separating the two plates?
The capacitor can discharge over the connecting wires; i.e., outside the capacitor. Some discharge can also occur over the dielectric, since it will not insulate completely.
What would be the purpose of connecting a parallel-tuned circuit into an antenna circuit?
The parallel-tuned filter in antenna circuit rejects only the undesired frequencies.
What is the purpose of connecting capacitor bank in series with 220 kv feeders?
A: Its purpose is to correct the power factor of the line.
How do you configure a monopole antenna on a frequency lower than the resonant frequency?
You can use an inductor or capacitor circuit to electrically lengthen or shorten the antenna. I cant remember which circuit does which but that's how antennas are efficiently used for several frequencies.
What is the next step after connecting TV converter box to rabbit ears and screen displays weak signal as a message?
Get a better antenna.
What are the benefits of having a digital antenna?
There are several advantages to having a digital antenna versus a dish antenna etc. With a digital antenna you don't have to worry about you signal fading in and out when you experience bad weather. Its a constant feed through a cable instead of rays bouncing from one satellite to the next.
Can you replace a 470uf 10v capacitor with a 470 25v 105c high temp radial leads capacitor for a digital tv converter box?
Yes, as long as there is room to mount the larger capacitor. A better replacement might be a 470uF 16v capacitor, which should be smaller than the 25v cap. If necessary, insulating tubing can be put on the leads & the cap can be mounted off the board, or at an angle to the board. Remember to observe polarity when connecting the capacitor leads to the board. Note the orientation & markings on the old capacitor before unsoldering it.
What are the two benefits of connecting a laptop computer to a docking station?
whats helps,condensation
How introduction of a die-electric increases the capacitance of the capacitor?
By connecting a capacitor in series the total dielectric thickness between the positive and negative terminals of the source, since you double dielectric thickness has effectively doubled, the total capacitance is one half of either capacitors.
How do you ground a CB radio antenna?
Grounding is accomplished by connecting a heavy cable from the ground side of the antenna to a ground rod. A ground rod is typically a 4 - 8 foot copper plated steel rod driven into the ground as close as possible to the antenna, making the wire connection as short as possible. All equipment should also be grounded to a rod, not just the antenna.
