●● 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?
