I only know two of lots. but the two is... oragami and kung fu

An open circuit does not work. You need to have a complete circuit for the electrical current to flow back to its source. For example: An open circuit occurs when a series fuse blows or a connector is unplugged.

R - Red

Y - Yellow

B - Blue

The secondary current is calculated by dividing the secondary current by the impedance of the load. This value shouldn't exceed the secondary-winding's rated current except for short periods of time.

Transmitting binary ones and zeros via IR (infrared) light is not as complicated as it may appear at first glance. Just as radio stations transmit information using radio waves, infrared devices transmit data using the infrared frequencies of the electromagnetic spectrum. Also, just as you need a compatible device to listen to a radio broadcast, you must have a device capable of understanding and translating incoming infrared signals. All sending and receiving IR devices contain small, dark windows called IR ports. Inside these ports, transceivers (a combination of a receiver and transmitter) send and receive data using the IR frequency. After a device's CPU (central processing unit) sends the binary ones and zeros to the software controlling the IR transmission process, that information is converted into pulses of IR light. The software then forwards the data to the device's transceiver, which transmits the IR signals to another IR port. The receiving device's IR software converts the infrared transmission back into binary digits. IR devices transmit the binary ones and zeros according to a protocol set by the IrDA (Infrared Data Association; http://www.irda.org). For high-data transmissions, such as from a laptop to a printer, both devices must be within a few feet of each other and the IR ports must be within each other's line of site. The data is sent in a 30-degree wide cone from one IR port to another. Depending on the IR software, a pulse of light could represent a digital one, while the absence of a pulse of light could represent a digital zero. High-speed IR devices don't actually transmit data in a serial string of ones and zeros, however. Rather, bits of data are sent in groups to speed up the transmission process.

1. Proper cable connection through a suitably rated starter.

2. No over load situation

3. Mechanically stable mounting and aligned well with the driven equipment.

4. Safety precautions to be taken based on the equipment driven by the motor.

To use for electrical currents or possibly store information. You can extract the gold be getting the computer chips and putting them in a glass jar with Mulatic acid and hydrogen peroxide. It should desolve the metals except the gold

Zero watts can be installed in 1000 micro farads. Watts are the product of amperage times volts. Micro farads is a value used in talking about capacitance.

A three phase panel will not give you 110 and 220 volts. A three phase four wire panel will, but not at these voltages. The nearest voltages will be 120 and 208 volts. The 120 volt is the wye voltage of 208 volts. 208/1.73 = 120 volts.

A single phase three wire panel will give you 110 and 220 volts.

To answer this question, wire size is rated in the amount of amperage that it can legally carry. Fuse sizing is based on the amperage that the wire carries.

The formula to find amperage when the HP is known is I = HP x 746/1.73 x E x %eff x pf.

A standard motor's efficiency between 5 to 100 HP is .84 to .91.

A standard motor's power factor between 10 to 100 HP is .86 to .92.

Amps = 30 x 746 = 55950 = 55950/ 1.73 x 415 x .87 x .87 = 55950/550 = 101 amps.

The electrical code states that a motor conductor has to be rated at 125% of the motors full load amperage. 101 x 125% = 126 amps

A #2 copper conductor with an insulation factor of 90 degrees C is rated at 130 amps.

Fusing for this motor will be, non time delay fuse 300 amps, time delay fuse 175 amps or a circuit breaker rated at 250 amps.

All motors should be test bumped to check for rotation. Larger three phase motors should be disconnected from the load before this is done.

Any device that uses the generator to supply its operating voltage is electrically classed as a generator load.

Twelve volts is not a common three phase voltage. Assuming that this is a hypothetical question any 1:2 ratio transformer will do the job.

Rather common for electric fork lifts

very small ones use 12v (hand stackers,pallet jacks)

larger ones are 24v 36v or 48v

the original transformers on the chargers usually run from 480V

and the chargers are specifically designed for the battery

most chargers use half wave rectifiers in a star configuration

600A thru a .7v drop for a diode is 500w loss, full wave is 1000w

regulation is switched from the primary side since its easier to handle the low current

To see if the motor is three phase or single phase look at the motor's nameplate. There it will tell you what the voltage needs to be and what system phase the motor needs to be connected to operate properly.
