In parallel, they both obviously have 220 v across them, so the 100 W bulb is obviously brighter than the 60 W one.

The 60 W bulb has more resistance, and in series they both have to pass the same current, so the 60 W has more voltage across it and might be brighter.

Different countries have made different decisions on the voltage and frequency of the electricity supply. A standard is necessary in each country to allow electrical equipment to be manufactured economically. Frequencies of 50 or 60 Hz are the only two standards used, and the nominal voltages vary from 100 v to 240 v for domestic supplies.

T430.247 of the NEC shows that a 1 hp motor operating at full load on 115v will draw 16 amps, called Full Load Current (FLC). Conductors supplying this motor are required to be 125% of FLC which is 20 amps.

Motor circuits are complicated things and do not follow the rules of other circuits. This motor, while drawing a maximum of 16 amps at full load and supplied with #12 AWG copper conductors can be protected by a breaker of 40 amps.

With a synchronous motor shorting the slip-rings together should make it work as an induction motor although perhaps not to an optimal degree.

The reason an AC voltage applied across a load resistance produces alternating current is because when you have AC voltage you have to have AC current. If DC voltage is applied, DC current is produced.

It isn't. It is only kept at maximum resistance when the motor is not running. That is done to limit the starting current.

The current is 1.4 amps, as already stated. The voltage is 45 x 1.4 volts.

because y phase is y phase ...it is not b phase or R phase so it is high

In Europe, where the voltage is 230 v (nominally), hand tools used on building sites commonly use a 110 v centre-tap supply for safety, with the centre-tap earthed so the maximum voltage to earth is 55 v.

Portable transformers with two 16-amp output sockets are often used and they can be found for about £30.

It depends on the voltage that the motor needs, because a higher voltage requires less current for a given amount of power. Also a higher voltage can tolerate a higher voltage drop. So there are two things that lead to a thinner wire when the voltage is higher.

"Electric Motor Warehouse", "American Electric Motors", "North Jersey Electro", "Square One" and "e-motor Pro" are great websites to check for this motor. You can also check eBay.

Starting capacitors are only required for single-phase induction motors. They are not necessary for three-phase motors.

Industrial servo motors control position. Higher functioning servo motors may also detect speed in addition to position. Controlling speed provides benefits rather than always functioning at full speed.

The the supply stays within +/- 5% of what the motor is rated for, you can do this.

The dielectric strenght of a transformer represents the maximum voltage permissible to apply across the transformer insulation i.e. between the transformer winding to another part of the transformer, normally the chassis or another winding and without break-down of the insulation ocurring (e.g. arcing).

The breakdown voltage of a transformer represents a voltage that exceeds its dielectric strenght and that causes breakdown e.g. arcing across the insulation.

A buck boost transformer is a type of transformer that is used to make adjustments to the voltage applied to alternating current equipment. These transformers are typically used in back up supplies or in tanning beds.

A shunt resistor is used to carry a majority of the electrical current away from the outlet. This causes the risks of electric shock to be down significantly, but still not completely gone.

EMF meters can be purchased online at dedicated sites such as 'LessEMF', 'Home Depot' and 'EMF Center'. Alternatively, you could try your luck with finding one on eBay or Amazon.

A mechanically powered flashlight , such as those with crank handles.

To calculate horsepower you need the car's torque numbers. To find the horsepower, the formula HP=(RPM*T)/5252. The "HP" stands for "horse power", the "T" in the formula stands for "torque " and RPM stands for the RPM values. To calculate the horse power of an electric motor, you use the formula HP= (V*l*eff)/746. V=voltage, l=amps, and eff= efficiency.

Ammeter is coneccted in series with circuit but Voltmeter is connected in parallel.

An indoor plant system includes: AC power system (input switch gear, standby plant, distribution system, and backup systems for uninterruptible loads and protective loads) and DC power system.
