Why is voltage not expressed in milli volts?
Voltage most certainly can be expressed in millivolts. Milli is simply an prefix that means one thousandth. I have seem picovolts, microvolts, millivolts, volts, kilovolts, megavolts and teravolts in common use. Other prefixes are also valid.
What is the measurements of 75 kva transformer 3 phase?
For a single-phase transformer, divide the ratedapparent power (expressed in volt amperes) by the voltage rating (expressed in volts) of the primary winding; this will give you the rated primary current (expressed in amperes) of the primary winding.
Why do electronics make ozone?
Any source of ionizing radiation makes ozone, and expressed voltages greater than 3 volts have the potential to make some ozone.
If a circuit has a resistance of 2000 ohms and has voltage of 30 volts what is the current expressed into metric units?
I=U/R so 30/2000=0.015 so 15 mA
Why electrical current arc through the ceramic insulator?
There may be a crack in the ceramic. Also, all insulating materials have a dielectric breakdown voltage, often expressed in volts per mil (0.001 inch). For example barium titanate ceramic breaks down at 75 volts per mil. Thus a 0.5 inch thick insulator of barium titanate ceramic will withstand up to 37,500 volts.
What is a voltage?
an electromotive force or potential difference expressed in volts.
What describes the energy possessed by electrons?
The energy of electrons is expressed in eV (electron volts).
Why is voltage not expressed in milli volts?
Voltage most certainly can be expressed in millivolts. Milli is simply an prefix that means one thousandth. I have seem picovolts, microvolts, millivolts, volts, kilovolts, megavolts and teravolts in common use. Other prefixes are also valid.
How do you calculate current capacity of transformer?
The secondary winding's current rating is the rated apparent power of the transformer (expressed in volt amperes) divided by its voltage rating (expressed in volts). This applies to both step down, and step up, transformers.
What is the ratio of electric current and voltage in the closed circuit?
The name given by engineers to the ratio of "electrical potential difference" (expressed in volts) to "rate of current flow" (expressed in amperes) is "resistance" (expressed in ohms).
What volts per bar in db is equivalent to volts per micro pascal in db?
I think 1 volt/bar when expressed in db you need to add 200 db to get reading in volts per micro pascal.
What is 1000 ohms?
"1,000 ohms" is the resistance of anything through which the current, expressed in amperes, is numerically equal to 0.001 times the potential difference between its terminals, expressed in volts.
What is the measurements of 75 kva transformer 3 phase?
For a single-phase transformer, divide the ratedapparent power (expressed in volt amperes) by the voltage rating (expressed in volts) of the primary winding; this will give you the rated primary current (expressed in amperes) of the primary winding.
Why are voltages are expressed in multiples of eleven?
They aren't in all cases. 110 volts is nominal and may range from 110 to 120 in a typical residence.
How many watts does 20 amps at 240 volts produce?
The unit of power is expressed in watts, and the product of current (Amps) and voltage (volts) is power there fore if you multiply the amps and the volts give watts. so 20 x 240 will give you a 4800 watts of power.
A battery has a difference in potential energy between the positive terminal and negative terminal which units express the difference?
The difference in potential energy between the positive and negative terminals of a battery is expressed in volts.
What type of meter is used to measure volts?
A voltmeter is used to measure voltage, which is typically expressed in units of volts. This device is commonly employed in electronic circuit testing and troubleshooting to determine the electrical potential difference between two points in a circuit.
