ANSWERS|100% CORRECT|GRADE A+
What is Ohm's Law? - ANSWER V=IR, it describes the relationship between voltage, current and
resistance
What is charge? - ANSWER Value for electricity flowing in a circuit
What is current? - ANSWER The rate of flow of charge
What is voltage? - ANSWER pressure that pushes electricity through an electrical circuit
What is resistance? - ANSWER opposition to flow
What happens when two positively charged particles are placed next to each other? - ANSWER The
charges will repel
What is a valence electron? - ANSWER a valence electron is an outer shell electron that is associated
with an atom
What is the difference between analog and digital circuits? - ANSWER Analog circuits utilize continuous
time signals, which means that an analog circuit has a response for almost every single value on the time
signal. Digital circuits utilize a digital signal, which can only be represented as 0 (off) or 1 (on). There is
only a response for these two states.
How do voltage and current behave in a parallel circuit? - ANSWER Voltage stays the same, current
divides proportionally.
How do voltage and current behave in a series circuit? - ANSWER Voltage divides proportionally and
current stays the same.
, What happens to current if the resistance in a series circuit doubles? - ANSWER The current will be
reduced by half.
What is DC current? - ANSWER Direct Current, a current that can only travel in one direction
What is AC current? - ANSWER Alternating Current, a current that can change directions
What is a capacitor? - ANSWER a component that stores charge
How do capacitors behave in series and parallel? - ANSWER Capacitors in parallel add up normally, but in
series are the inverse of the sum of their inverses
What do capacitors oppose? - ANSWER Capacitors oppose a change in voltage. This is due to the
capacitor's time constant which makes it so that any sudden changes in voltage will be subjected to the
capacitor having to charge first.
How do capacitors behave at low and high frequencies? - ANSWER At low frequencies they act as an
open circuit, and at high frequencies they act as a short. This is due to the capacitor's time constant
where at low frequencies it takes the capacitor so long to charge it is like an open circuit, but at high
frequencies it charges and discharges so quick it acts as a short.
What is an inductor? - ANSWER A component that has the ability to concentrate a magnetic field
How do inductors behave in series and parallel? - ANSWER Inductors in series are the inverse of the sum
of their inverses, but in parallel add up normally
What do inductors oppose? - ANSWER They oppose changes in current.
How do inductors behave at low and high frequencies? - ANSWER At low frequencies, inductors become
a short circuit, and at high frequencies it becomes an open circuit.
