Why capacitors cannot be used with direct current?
DC does not travel through a capacitor for long because there is a buildup of charge on the plates and when the voltage matches the supply voltage, mo more current flows. But capacitors are used to smooth a DC supply because a capacitor acts a bit like a small battery and can prevent any rapid fluctuations in the supply voltage.
What value of Vce would you expect if the base terminal of a transistor were open?
If the base terminal of a transistor is open, the transistor will be in an off state, meaning it is not conducting. In this condition, the collector-emitter voltage (Vce) would be expected to be approximately equal to the supply voltage, as there is no current flow through the collector-emitter path. Hence, Vce would be close to the maximum supply voltage applied to the collector.
HOW DO FILTERING CAPACITORS WORK?
Filtering capacitors work by smoothing out fluctuations in voltage within a circuit, particularly in power supply applications. When placed in parallel with the load, they charge up during voltage peaks and discharge during dips, effectively reducing ripple and providing a more constant voltage output. This action helps to filter out high-frequency noise and stabilize the voltage, ensuring that electronic components receive a steady power supply. By storing and releasing energy, filtering capacitors enhance the performance and reliability of electronic circuits.
How capacitor helps to improve the ripple factor?
A capacitor helps improve the ripple factor in power supply circuits by smoothing out the fluctuations in voltage that occur after rectification. When connected in parallel with the load, the capacitor charges during the peaks of the rectified voltage and discharges during the troughs, effectively reducing the voltage ripple. This results in a more stable DC output, which is particularly important for sensitive electronic devices. By minimizing the ripple, the capacitor enhances the overall performance and reliability of the power supply.
Why you tapchanger fix in transformer hv side?
A tap changer is used on the high voltage (HV) side of a transformer to adjust the voltage ratio and maintain a desired voltage level under varying load conditions. It allows for voltage regulation and compensates for voltage fluctuations in the power system. By changing the number of turns in the transformer winding, the tap changer can increase or decrease the voltage output, ensuring a stable and reliable power supply.
How can I prevent voltage fluctuations in my house to protect my electronic devices and appliances?
To prevent voltage fluctuations in your house and protect your electronic devices and appliances, you can use surge protectors, voltage regulators, and uninterruptible power supply (UPS) systems. These devices help stabilize and regulate the voltage supply to your devices, reducing the risk of damage from sudden spikes or drops in voltage. Additionally, ensuring proper grounding and wiring in your home can also help prevent voltage fluctuations.
What causes voltage fluctuations in an electrical circuit?
Voltage fluctuations in an electrical circuit can be caused by factors such as variations in the power supply, changes in the electrical load, or issues with the wiring or connections in the circuit. These fluctuations can lead to unstable voltage levels, which may affect the performance and safety of electrical devices connected to the circuit.
What causes high voltage fluctuation in domestic power supply?
High voltage fluctuation in domestic power supply can be caused by factors such as abrupt changes in power demand, issues with the power grid infrastructure, faulty transformers, or fluctuations in the supply of electricity from the utility company. These fluctuations can lead to damage of electrical devices and pose a safety hazard to appliances. Using voltage stabilizers and surge protectors can help mitigate the impact of high voltage fluctuations.
How long does a incandescent light bulb last?
It depends on the quality of filament, how often it is switched on and off and fluctuations of supply voltage.

DC does not travel through a capacitor for long because there is a buildup of charge on the plates and when the voltage matches the supply voltage, mo more current flows. But capacitors are used to smooth a DC supply because a capacitor acts a bit like a small battery and can prevent any rapid fluctuations in the supply voltage.
Can a 120 volt fluctuation into a house be stablized by a voltage stablizer and if so what is it that should be purchased?
There is always voltage fluctuations in home voltages. It is due to loads coming on and going off line on the primary distribution supply. The utility company is mandated to maintain a plus or minus voltage of 10%. If the voltage is within this range no voltage stabilizer is needed.
What voltage would you expect to measure on a red wire from a power supply?
The voltage on a red wire from a power supply typically depends on the specific power supply being used. Common voltages for red wires in power supplies include +5V, +12V, and +24V, among others. It is important to check the specifications of the power supply to determine the exact voltage.
How can you get 12volts supply from speaker?
You can not. Speakers do not supply a voltage they need a voltage to operate correctly.
What are the benefits of installing a voltage regulator for home use?
Installing a voltage regulator for home use can help protect your electronic devices from damage caused by power surges or fluctuations. It can also ensure a stable and consistent supply of electricity, which can improve the performance and lifespan of your appliances.
Does the speed of a split phase motor changes appreciably with a change in the applied voltage?
The speed of a split-phase motor is directly proportional to the frequency of the power supply, not the voltage. As long as the frequency remains constant, the speed of the motor will remain relatively stable regardless of minor fluctuations in voltage within normal operating limits.
Do you add electrical supply voltage and induced voltage of a coil to get total voltage on the coil?
The induced voltage acts to oppose any change in current that is causing it. So, if the current is increasing, then the induced voltage will act in the opposite direction to the supply voltage; if the current is decreasing, then the induced voltage will act in the same direction as the supply voltage.
How many watts will be neede to supply 400 amp welder?
It depends on the supply voltage watts = current in amps times the supply voltage
