In the US a service drop transformer (on the pole or underground) converts the distribution voltage to 220VAC center tapped, which provides two opposite phased 110VAC outlet and lighting use and/or one 220VAC single phased high power for heating and cooking use. Occasionally 230VAC center tapped or 240VAC center tapped is provided instead of 220VAC.

What happens to supply voltage if additional resistance is connected in parallel circuit?
The supply voltage in a parallel circuit remains the same regardless of the number of additional resistors connected. The voltage across each resistor in a parallel circuit is the same as the supply voltage. Adding more resistors in parallel will increase the total current drawn from the supply.
The voltage across a short circuit is equal to?
zero? the supply voltage? the supply voltage minus the individual coltage drops? the sum of the individual voltage drops? which one?
How much voltage does each branch of a parallel circuit?
Yes. The voltage across every branch of a parallel circuit is the same. (It may not be the supply voltage, if there's another component between the power supply and either or both ends of the parallel circuit.)
How is the voltage of the power supply for a series circuit calculated?
The circuit by itself doesn't determine the voltage of the power supply. If there's some additional requirement that goes along with the circuit, such as "The current through the circuit must be XYZ amperes.", or "The voltage across the third component from the north end of the circuit shall be ABC volts,", then that requirement would dictate the power supply voltage. But in order to calculate it, you'd need the knowledge of every component in the series circuit.
How does increasing the voltage of a supply in a electromagnet affect the strength of the magnetic field?
Increasing the voltage of a supply in an electromagnet increases the current flowing through the coil, which in turn increases the strength of the magnetic field produced by the electromagnet. This is because magnetic field strength is directly proportional to the current flowing through the coil.
What happens when current travels through the second transformer before entering your home?
When current travels through the second transformer before entering your home, it undergoes a further step of voltage reduction and may be adjusted for the specific requirements of the local distribution network. This helps ensure a safe and consistent supply of electricity to your home at the appropriate voltage levels for your appliances and devices.
How does the number of bulbs affect the amount of electrisaty in a circuit?
Adding additional lamps has no effect on the supply voltage supplied to you home. If the lamps are connected in series, then the sum of voltage-drops appearing across each lamp will equal the supply voltage. If the lamps are connected in parallel, then the voltage across each lamp will equal the supply voltage.
What causes speed drop in motor?
1) If current, at 'on load' condition, reach or cross its rated value, then the speed of the motor will be decreased. 2) If there is any voltage droop occurs in the incoming supply then the speed of the motor will be decreased.
How decreased blood supply effect muscle activity?
Decreased blood supply in the muscle can cause anoxia then paralysis.
What is the term for decreased blood supply?
Ischemia is the medical term meaning decreased blood supply. Prolonged ischemia can lead to infarction.
How can you get 12volts supply from speaker?
You can not. Speakers do not supply a voltage they need a voltage to operate correctly.
Why speed is decreased when field current increases in dc motor?
Because with more field, the armature produces the same voltage at less speed. The voltage generated by the motor must always be less than the supply voltage. A motor that is driven faster than it wants to go becomes a generator.
What is the main of flame trap?
A device that prevents a gas flame from entering the supply pipe.A device that prevents a gas flame from entering the supply pipe.
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
What are the main purposes of the battery?
to provide current to start vehicle and supply modules with voltage before start up
What is the Difference between supply voltage and input voltage?
no difference...
