Why dc components operate at low voltage compared to ac component?

Because equipment operating on DC is usually low-power electronic equipment, and it uses a power-supply to convert the house AC supply to DC at the right voltage.
Most appliances needing high power are designed to run on AC because that is the normal supply to houses.

What is the example of passive component?
Passive components are components that don't require power being applied in order for them to work. A transformer would be considered an active component because it requires power to operate, while a capacitor, resistor and similar items are considered passive, and many perform multiple functions. For instance, a capacitor will pass AC while storing DC, a resistor can be used to limit voltage or current, etc.
What is true about the sum of the voltages across the components in a circuit compared to the voltage of the cell?
voltage is devided only in series circuit and is the same at the parallel circuit
How should a voltmeter be connected to measure voltage of a component?
Since voltage is electrical potential difference, to measure the voltage across a component, you place the voltmeter across, or in parallel with, the component.
What components compose the excitation current of a transformer. How are they modeled in the transformer 's equivalent circuit?
The magnetization current can be broken-down into two components: the first is in phase with the supply voltage and is responsible for the losses, whereas the second component lags the supply voltage by 90 degrees and in responsible for the magnetic field.
When transformer voltage regulation will be zero it operate at?
A transformer will operate with a voltage regulation of zero when it is not supplying a load.

Where are resistors placed to control voltage and current?
A: A RESISTOR is a passive component it cannot control voltage these components and/or current it can however limit

What is total voltage in a series circuits?
In a series circuit the total voltage is the sum of the voltage drops across all the component in series. When the voltage drops across each the individual components are added up, they will equal the supply (or applied) voltage.
What do individual components in a parallel circuit experience the same of?
The voltage is the same across every individual component in a parallel configuration.
What are the significance of computer peripherals in computer system?
The different peripherals are designed so that one component may fit one slot but not another. This is due to the different voltages certain components require to function. There for if you plug a component into a lower voltage peripheral then it would not work and if you plug a component into a higher voltage peripheral then it poses a fire hazzard as to much voltage can cause over heating and component failure.
Is line voltage understood as any voltage?
Line voltage is understood as the voltage that the device or appliance needs to operate on. It is also referred to as the devices working voltage. Once the proper line voltage or working voltage is applied to the device it may be transformed to different voltages for different internal component circuits.
What is passive device?
A passive device is a component that does not require power to operate. A lightning arrester on high voltage lines would fall into this category.
Give the characteristics of a parallel circuit?
-- The voltage across every circuit element is the same, and is equal to the power supply voltage. -- The current through each circuit element is in inverse proportion to its impedance. -- The sum of the currents through all circuit elements is equal to the power supply current.
What are the components of a generator?
The rotor, the stator and the voltage regulator are three main components of a generator. If you are talking about a motor generator set then of course the other main component would be the engine to drive the generator.
What happens if you drive around with a bad car voltage regulator?
Battery will either be overcharged and burn out numerous electrical components or battery will be undercharged and eventually won't have enough voltage to operate vehicle
Why zener used as reglator?
Zeners are manufactured to have exact reverse breakdown voltage. All this means is if a 10 volt Zener is installed in series with a load dropping resistor, and a voltage higher than 10 volts is across both components, the Zener will breakover and present that 10 volts to any component in parallel with it. Volts go to 20, Zener holds at 10, resistor sees the other 10 volts. Zeners operate safely in the breakover region while normal junction diodes operate in forward voltage.
