What is amperage input of transformer on 208 3 phase?
The amperage input of a transformer on a 208V three-phase system can be calculated using the formula: Amperage (A) = Power (Watts) / (Voltage (V) x √3). To determine the amperage, you need to know the power rating of the transformer in watts (or kilowatts). Once you have that, you can plug the values into the formula to find the input amperage.
When using a step down transformer is amperage affected?
Yes, when using a step down transformer the amperage is affected.
How do you measure voltage using a ammeter?
An ammeter measures amperage not voltage.
Is sicence and technology related?
Yes because if you use ELECTRICITY for the technology then you are using science (lightening, power stations, circuits, batteries). Ps I'm not entirely sure tho!
Why electrodes get red hot during welding?
They shouldn't. When using the correct electrode and amperage they will get hot but not red hot. Uncoated electrodes do get red hot but are not used in most applications. Too much amperage is usually the problem.
Ow do you calculate amperage with watts and volts?
You can calculate amperage (A) using the formula A = W / V, where W is the power in watts and V is the voltage. Simply divide the power in watts by the voltage to find the amperage.

If kilowatts are known how to you find the proper wire size?
Wire size needed depends on amperage, not watts. If you know the voltage of the power supplied you can calculate the amperage using this form of the "power formula":A = W / VThen there are tables that tell the amperage each wire gauge is capable of carrying. Just select the gauge that has the amperage rating just larger than you calculated.
How can you use matrices to solve real world problems?
Matrices are tools to solve linear equations. Engineers use matrices in solving electrical problems in circuits using Thevenin's and Norton's theories.
When using a step down transformer is amperage affected?
Yes, when using a step down transformer the amperage is affected.
Does using a higher than necessary ampacity in electrical circuits cause a higher electrical meter reading?
No, the electrical meter reads watts by multiplying the voltage and the amperage used in electrical circuits. Using oversize wire does not govern the amperage flow to the load. The load resistance in the circuit is what governs the amount of current that flows through the wire. This current in the load circuit is multiplied by the voltage applied to the circuit at the electrical meter. The product of this multiplication is wattage, multiplied by the amount of time the load is on, is what the electrical utility bill is based on.
Explain the rheostat and its advantages in electric circuits?
Advantages in electric circuits : Advantages of using the rheostat in electric circuits is optional as you could just use the dial on the power-supply to vary the voltage (p.d.), and therefore the current. The advantage of using the rheostat is that you can control it to give you nice even numbers for the voltage.
What is the Power Triangle?
In electrical systems using AC (Alternating Current), circuit elements can experience reversals in the directional flow of energy. (AC reverses current direction many times a second.) This results in less power delivered to the circuits than would be indicated by the input voltage and current (amperage). The apparent power, as indicated by voltage and amperage, is represented as the hypotenuse of a right triangle. The other sides of the triangle are the real power (usable energy in watts) and the reactive power (which is returned to the generating system). Reactive power, therefore, is the energy not available to do work. Using the Pythagorean theorem, the relationship between the three energy amounts is: (apparent power)2 = (real power)2 + (reactive power)2 Ideally, reactive power would be the smaller of the two component energies. The ratio of real power to apparent power is called the Power Factor (ranges from 0 to 1 ), and can be increased by reducing the reactive power through proper system design.
Advantages of using integrated circuits?
As opposed to discrete components or vacuum tubes:-Small size.Low power consumptionEase of mass production
How many watts is an 18volt power tool?
To determine the wattage of an 18-volt power tool, you need to know its amperage (current). Wattage is calculated using the formula: Watts = Volts × Amps. For example, if the tool draws 5 amps, the power would be 90 watts (18 volts × 5 amps). Without the amperage, you cannot calculate the exact wattage.
How do you convert voice message to text message using electronics circuits?
It is only possible by using voice-to-text software, you cannot do it using electronic circuits.
Anything wrong with using a car battery that is half the amperage?
no
