Which is an electrical potential difference between objects. The electromotive force.
Voltage
Ohms law is: Voltage/ resistance= Current. T or F?
True
The unit measurement of Inductance is…
Henry (L)
Unit measurement of current.
Ampere (amp)
The Sum total of all the forms of resistance in an AC circuit is known as…
Impedance
An Audio current is…
A.C. - Alternating current
Allows current to easily pass is called…
a conductor
The ability for an object to hold an electrical charge is called:
Capacitance
Current produced by a battery is…
D.C. - Direct Current
Is described as the opposition to flow of current
Resistance
Blocks D.C. and passes A.C. Can also store an electric charge…
Capacitor
Only allows current to flow in one direction…
Diode
Passes D.C. and add resistance to A.C. You make transformers out of these…
Inductors
The word is Potentiometer, most of the time we call them…
pot
What is the unit measurement for Capacitance?
Farad
Surface mount is the method of constructing electronic circuits in which the components are mounted directly onto the surface of a printed circuit board T or F?
True
Can transform or step a voltage up or down is a
Transformer
When referring to pots, an “audio” tapper is…
Logarithmic
An electrical component that opposes current. Unit measurement is ohms, is called…
Resistance
Which of the below uses the unit measured “ampere.”
Current
A complete electronic circuit made by the patterned diffusion of trace elements into the surface of a thin semiconductor material is called an IC (Integrated Circuit).T or F
True
Michael Faraday discovered the natural behavior of energy called, electro- _______ induction
magnetic
