Is a transformer one source of constant electric current?
A; Terminology is not correct a transformer is not really a source but rather a device to transform one source of power to some power that can be used as required minus efficiency of power transfer
What is the name of an electric current that flows in one direction?
That's a "direct" current.
Rate of flow of electric charge is measured in?
Electric current is the rate of charge flow past a given point in an electric circuit, measured in Coulombs/second which is named Amperes. In most DC electric circuits, it can be assumed that the resistance to current flow is a constant so that the current in the circuit is related to voltage and resistance by Ohm's law. The standard abbreviations for the units are 1 A = 1C/s.
Why does the current rise when the voltage drops?
It is not generally true that current increases when the voltage decreases. Ohms law for a simple resistor says that current is proportional to voltage. However an electric motor supplying a constant mechanical load power will readjust to a lower supply voltage by drawing more current, although if the voltage is progressively reduced the motor would stall. Switch-mode power supplies also tend to draw a constant power from the supply when the input voltage changes.
What do a direct electrical current is different from an alternating current because only the direct electrical current means?
In Direct Current, electrons flow from the negative pole of the electrical source, through the load, to the positive pole of the electrical source. Current is constant as there are no variations in voltage over time in the circuit. Voltage and current are measured by directly measuring the voltage and current in the circuit. In Alternating Current, electrons also flow from the negative pole of the electrical source, through the load, to the positive pole of the electrical source. However, the polarity of the poles changes +/- to -/+ to +/- , alternating polarity over and over again. This causes the direction of the electrons in the circuit to change each time the source poles change polarity. Current and voltage are not constant in an AC circuit as they vary with the waveform generated by the electrical source. In many, but not all cases, voltage and current are measured by the RMS (root-mean-square) method as directly reading the peaks of the AC waveform will not indicate the correct amount of energy in the circuit.

What is one source of constant electric current?
Cells and batteries.A more detailed answerIn general, most power supply sources - including cells and batteries - cannot supply either a truly constant current or voltage.Because most load devices are designed to require a nearly constant voltage - and not a specific constant current. - most power supplies - including cells and batteries - are designed to supply a given output voltage whatever the current that is being drawn, provided of course that the current stays within a pre-determined designed range of output current values.One definition of "constant current source" is that it has zero output resistance, which in practice cannot exist.However, a transistor can act as a constant current source if biased and used in that manner. This can also be done using one of the several standard "voltage regulator" components - which are available from electronics parts suppliers - because they can be hooked-up to act as constant current sources to operate over a small range.
What is the path for transmitting electric currents?
Electric currents flow from the source through the circuit and back to the source in materials called conductors.
How does static electric differ from current electric?
Static electricity is a charge that is stored in a medium until it finds a way to discharge itself to a ground source .. scuffing your feet on a rug , socks help , will build a charge in you until you touch something ,, brother, door knob , lightening is a static charge, a capacitor uses a static charge Electric current is a constant flow of electricity from one place, a source thru a circuit and back to the source .. a battery is made to cause this flow thru chemical action .. the power in your house has various circuits that carry the electrical current flow thru the devices and appliances in your home
What current flows in one direction while anther remains constant?
In one direction - or constant - is called direct current. The other sort is called alternating current.
Can an electric current generate an electromagnetic wave?
Not a constant electric current but a changing one will generate electromagnetic waves.First: If you have a lone electron, and it is accelerated in any way, it will send off an electromagnetic wave. This is because a changing electric field generates a magnetic field.It is also true that changing magnetic field will generate an electric field. This is the reason that if you have an electric current, which is generating a magnetic field, and you change the current you generate an electromagnetic wave. To generate a continuous sinusoidal electromagnetic wave you continuously change the current sinusoidally.
Name one household items that use a battery as a source of electric current?

What is the formula of getting leakage current?
There are several formulas to find out leakage current, but one is the general electric current equation. This electric current equation is I=Qt.
What does a current and coulomb have in common?
A coulomb is the charge caused by a constant current of one ampere (what current is measured in) in one second.
