What is analog rail?
The positive and negative supply voltages. Analog amplifiers clip a few volts short of their voltages, so these two supplies are usually 12 volts or more.
What supplies power to a computer?
The "power supply" supplies power to a computer. A computer's power supply is a "switchmode power supply" responsible for converting the AC voltage from the wall into several DC output voltages.
How efficient is a transformer when changing voltages?
A: Must understand this A transformer transfer power minus efficiency to another level that all it does.
What is the Makita Battery Charger used for?
The Makita Battery Charger is used for Makita batteries. This battery charger is capable of charging many batteries depending on the voltages for the batteries.
What are the voltages for a ATX power supply?
the ATX standard supplies three positive rails: +3.3 V, +5 V, and +12 V
What voltage is commonly found in homes?
In North America 120/240 is the main voltages used. It is known as a three wire system. L1 to L2 supplies 240 volts. L1 to N supplies 120 volts and L2 to N supplies 120 volts.
Does Florida Have AC or DC power supply?
All electricity supplies are a.c. D.C. is used, on occasions, for long-distance transmission (or undersea transmission) at very high voltages, but never for power supplies to homes or businesses.
What is the need for power supplies?
A power supply is needed to transform the line voltage (e.g. 120 VAC 60 Hz, 240 VAC 50 Hz) to the voltage or voltages needed by the equipment (typically DC voltages between 3 VDC to 300 VDC) depending on the operational requirements of the equipment. Some old vacuum tube equipment needed low voltage AC to heat the vacuum tubes, the power supply then also had to provide these voltages (e.g. 6 VAC, 12 VAC). I have seen power supplies as simple as providing just one DC voltage to power supplies as complex as providing 20 to 30 different DC voltages, some positive and some negative with respect to ground.
What can cause a faulty power supply?
A faulty power supply does not supply any power at all to a computer or supplies incorrect voltages. Most of the time faulty power supplies are not serviceable and require replacement.
Why don't have 2phase supply?
Two-phase supplies, in which the phase voltages are displaced from each other by 90 degrees, are less economical than three-phase systems.
What should be real and reactive power flow through the transmission line when the sending end and receiving end voltages are of same magnitudes and phase angles?
The power transfer equation is this:P = V1*V2*sin(phi)/Xt,V1 = source 1 voltageV2 = source 2 voltagephi = angle between the two sourcesXt = transfer impedance, the impedance of the line + both source impedancesFrom this you can see that if the angle between the two sources is 0, then the power transferred would be zero as well.Reactive power flow *should* be zero if perfectly matched as well, although there will be a small amount of reactive power usage due to line charging (charging current).
What is electrical checks?
The term electrical checks will differ with respect to the machine or system being referenced. Electrical checks on a car will include the DC battery Voltage, charging voltage and current and may be voltage during engine starting. On a machine it could be main voltage secondary control voltages and even specific test point voltages on a control board.
