What is Magnitude of the voltage or current?
"Magnitude" means how strong it is - how much voltage (how many volts), or how much current (how many amperes).
Which power is product of voltage and current in a circuit calculated without considering the phase shift that may be present between the voltage and current?
I'm not sure there is a term other than "power"; V*A, or the vector sum of real and reactive power is equivalent to the power calculated by multiplying the voltage times the current, ignoring phase shift.AnswerThe product of voltage and current in an a.c. circuit is called 'apparent power', expressed in volt amperes, in order to distinguish it from 'true power' (in watts) and 'reactive power' (in reactive volt amperes).
What is the formula of electric current?
the formula for electric current is VI ,where v is voltage then I is the current. the unit used for current is ampere and volts for voltage. multiply the total I to the Voltage The formular of electric current is given by I=V/R ,I=P/V
What is the power dissipated by a resistor that has 5 amps flowing through it with 120 volts applied?
The power in a resistor (in watts) is simply the product of the current (in amperes) times the voltage (in volts).The power in a resistor (in watts) is simply the product of the current (in amperes) times the voltage (in volts).The power in a resistor (in watts) is simply the product of the current (in amperes) times the voltage (in volts).The power in a resistor (in watts) is simply the product of the current (in amperes) times the voltage (in volts).
What are the quantities and unit related to omh's law?
Ohm's Law relates three key electrical quantities: voltage (V), current (I), and resistance (R). Voltage is measured in volts (V), current in amperes (A), and resistance in ohms (Ω). The law is commonly expressed by the formula V = I × R, indicating that the voltage across a conductor is directly proportional to the current flowing through it, given a constant resistance.
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).
Is emf current greater than current?
EMF is electromotive force. It is another name for voltage. Voltage is electric potential in joules per coulomb. Current is electric flow, in amperes. Amperes are coulombs per second. Voltage and current are not the same thing, and "emf current", or "voltage current" does not make sense.
Is units of electric current a volt?
Electric current is measured in amps not voltsElectric voltage is measured in volts.
What is Alternating current is measured in?
Alternating Current is measured in Amperes.
Is The units of electric current is the volt?
NO! (the units of electric current is Amperes).
What is the method for calculating amperes and current?
To calculate amperes, you can use Ohm's Law: amperes = voltage ÷ resistance. Current is the flow of electric charge, measured in amperes, that passes through a conductor in a unit of time. You can measure current using an ammeter in a circuit.
How do i fine an expression for power that involves only current and voltage?
You do not need ohm's law to relate power to current and voltage. Power is current times voltage. If you know current and voltage, you do not need to know resistance.
What is measured in amperes a current voltage or an Resistance?
Electrical current is measured in amperes.
What is the difference in the current and voltage?
Current (amperes) is the rate of flow of electric charge, in coulombs per second. Voltage, on the other hand, is the electric potential of that charge, in joules per coulomb.Current and voltage are related to resistance by Ohm's Law, which states that voltage is equal to current times resistance.There is a tendency to misuse the term "current", and to apply it, for instance as "an electric current of 120 volts". This usage is incorrect. Current is current, and voltage is voltage, as noted above.
What does the term voltage and current mean?
Voltage -the rate at which energy is drawn from a source that produces a flow of electricity in a circuit; expressed in voltsCurrent - a flow of electricity through a conductor; "the current was measured in amperes"
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.
How does electric current travel?
Electric current travels through a closed circuit, flowing from a higher voltage to a lower voltage. It moves through conductive materials such as wires, where the flow of electrons creates the electric current. The rate of flow of electric current is measured in amperes.
