Important considerations when choosing power supplies are type of output, regulated or unregulated. Regulated means the Voltage will stay constant (at least while the supply is operating within its specification) irrespective of the load. Unregulated supplies tend to have higher outputs than stated and are normally used with equipment that has it's own internal regulation circuitry. If in doubt always choose a regulated supply. Using Voltages higher than recommended for a particular piece of equipment may cause permanent damage. Where Wattage or VA rating is quoted this often refers to the total wattage available for a power supply. This figure is mostly used for multi rail units, so that when the VA is calculated for each output and then added together, the total Wattage / VA should not exceed the makers rating.

4 What is the difference between a transformer and a rectifier Which are found in a PC power supply?
A rectifier is a device that converts alternating current to direct current. A transformer is a device that changes the ratio fo current to voltage. A rectifier is found in a PC power supply.
What type of transformer is used in a phone battery charger and its ratings?
Usually these "wall wart" chargers are small switching regulated power supplies, not transformers. A transformer may be part of the switching regulator circuit, but it is only one small part of it.The ratings of the switching regulated power supply will vary with different types of phones, but are always printed on a label on the "wall wart" casing. Read the label.
What is the difference between phase angle and phase difference?
Although we use the term 'Phase angle' it's also an angle referred to another phasor (voltage or current).For example,conventionally when expressing power factor, we use 'voltage' as the reference. So the 'phase angle' of a particular phasor is the phase difference between our reference (voltage) & the phasor.As the gist, both mean the same except that 'phase angle' is the direction of the phasor w.r.t. positive x direction (reference)..AnswerBy definition, phase angle is the angle by which a load current leads or lags a supply voltage.Phase difference is the angle between any two electical quantities -for example, the angle two phase voltages of a three-phase system.
Relationship between demand and supply?
1:inverse relationship between supply and demand 2:supply depends upon the demand of a commodity, that it might be positive or negative. 3:supply always depends upon demand but demand never depends to supply. 4:a supply never affects the demand of a commodity but demand always affect to its supply. 5:demand is the initial stage but supply is the stage after demand. 6:supply have a positive relations to price whereas demand has a negative relations with price. 7:supply and price has a direct relations or positive relation. 8:law of supply relates to the price and supply of a particular commodity in a particular time period. 9:price has a connections with demand and supply that it affects both supply in a positive way and demand in a negative way and if price changes then both demand and supply will change. 10:demand curve shows the changes positions of demand in a different price level of a particular commodity where demand schedule also shows the changes positions of demand in a different price level of a particular commodity, hence both have a common objectives to depict the same result in a different way.
Difference between line driver and push pull circuit?
Line Driver A line driver is a sourcing output. When in the on state, a line driver will supply Vcc. In the off state, a line driver will float. Because of this, a sinking input is required for proper operation. Open Collector An open collector is a sinking output. In the off state, an open collector will supply a path to ground. When in the on state, an open collector will float. For proper operation, a sourcing input is required. Push-Pull A push-pull output is a combination of a line driver and an open collector. In the off state it will supply a path to ground and in the on state it will supply Vcc.
