What else can I help you with?
When an alternating voltage is applied to purely resistive circuit what happens?
When an alternating voltage is applied to a purely resistive circuit, the resulting current is in phase with the voltage.
Does vac stand for volt amp current or volt alternating current?
Vac usually stands for voltage alternating current. It represents the voltage of an alternating current electrical system.
Can alternating current be expressed as a vector?
In the case of AC, you can express the current, the voltage and the equivalent to the resistance (called "impedance" in this case) as a vector - with a magnitude, and a phase angle.
What does electricity refer to?
It is the complex ratio of the voltage to the AC (alternating current) circuit. It extends the concept of resistance to AC circuits due to magnitude and phase.
What is the voltage of alternating current?
60 Hz
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).
What does electrical impedance refer to?
It is the complex ratio of the voltage to the AC (alternating current) circuit. It extends the concept of resistance to AC circuits due to magnitude and phase.
What is Alternating current is measured in?
Alternating Current is measured in Amperes.
What is alternative voltage?
Alternating voltage is the E.M.F. and is one whose magnitude whose magnitude changes with time and direction reverses periodically. The instantaneous value is given by E=Eo sin w t, where,E=value of alternating voltage at time t Eo = maximum value of alternating voltage(amplitude) w=angular frequency of supply.
Ac voltage applied across a load resistance produce alternating current?
The reason an AC voltage applied across a load resistance produces alternating current is because when you have AC voltage you have to have AC current. If DC voltage is applied, DC current is produced.
What are the uses of alternating current?
voltage can carry current a further distance.
What are the kinds of voltage?
Alternating current - AC, and direct current - DC.
