Basic AC
What does AC stand for in electronics
Alternating current
What is the unit of measurement for Capacitance?
Farad
What is the unit of measurement for Inductance?
Henry
what is reactance
the opposition to AC current flow caused by both capacitance and inductance
What company is guest speaking Friday
Duncan aviation
what's the name of the good transformers
Autobots
Name one major difference between AC and DC
AC voltage reverses direction, while DC maintains a constant direction
Total capacitance in a series circuit is
the inverse of the sum of all capacitors
What is the designation for inductive reactance?
XL
what is the symbol for Impedance
Z
what two places are we going on our field trip next week
Western and Duncan
What is the purpose of a transformer in an AC circuit?
To change the voltage levels
What is frequency measured in
Hertz
The formula for total capacitance in a parallel circuit is:
the sum of all the capacitors
The opposition to current flow offered by an inductor is called?
Inductive reactance
The opposition to current flow offered by a capacitor is called?
Capacitive Reactance
who was the pioneer for AC electricity?
Nikola Tesla
what are the three parts that make up a transformer
Primary coil, Secondary coil, core material
What does an inverter do?
changes DC to AC
What is the designation for capacitive reactance?
XC
Producing a magnetic field that holds current flow steady is a characteristic of what?
an inductor
If a circuit contains 70 ohms of inductive reactance and 20 ohms of capacitive reactance, what is the net reactance
50 ohms inductive
What is Mr Trampers favorite airplane?
V-tail bonanza
what is the formula for finding wire turns in a transformer
Vin/Vout=Tp/Ts=Iout/Iin
What is instantaneous voltage
the voltage at any single point in a sin wave
in a AC circuit what happens to current flow as it goes through a capacitor?
the capacitor will steady out the voltage
In an inductive reactance circuit, what happens to Xl if Frequency increases
it increases
Define resonance in an AC circuit
It's the condition where inductive and capacitive reactance are equal, leading to maximum voltage or current
what is the airport identifier for Sparta airport
8D4
what are the three types of transformers we learned about
step up/down and polyphase
This is unwanted loss due to power that is consumed by reversing the magnetic field of a inductor each time the direction of current happens; it is also known as lag
Hysteresis
What will capacitve reactance do in a circuit if Capactiance is increased?
it will decrease
in a AC series circuit what happens to our current in an inductor
no current can pass
Impedance is the
Total opposition to the flow of AC
what's the formula for calculating power?
P=IxE
A transformer acts off what property?
inductance
