●● True or False: Direct current reverses direction at regular intervals.
Answer: False
The *electrons* will move in a *counterclockwise* path around the
circuit and *only one direction* inside of the wire.
Positive to Negative
●● For a collection of resistors that are connected in *series,* which of
the following statements is *true?* Assume that the resistance of each
resistor is different.
a) The current through each resistor is the same
b) The equivalent resistance is equal to the sum of the individual
resistances
c) The total voltage across the circuit is equal to the sum of the
individual voltages
d) All of the above are true
Answer: a) The current through each resistor is the same
b) The equivalent resistance is equal to the sum of the individual
resistances
, c) The total voltage across the circuit is equal to the sum of the
individual voltages
*d) All of the above are true*
●● True or False: Kirchhoff's *Loop* Rule states that the sum of the
potential differences around any closed loop in an electric circuit is
always greater than the current in the circuit.
Answer: False. Kirchhoff's *Loop Rule* states that the *sum of the
electric potential differences* (voltages) around any *closed loop is
zero.*
●● For a collection of resistors that are connected in *parallel*, which of
the following statements is true? Assume that the resistance of each
resistor is different.
A) The sum of the current through each resistor is equal to the total
current of the circuit.
B) The equivalent resistance is equal to the sum of the individual
resistances.
C) The total voltage of the circuit is equal to the sum of the voltages
across each resistor.
D) A, B, and C are true.
Answer: A) The sum of the current through each resistor is equal to the
total current of the circuit.
