Answers Inverse Propotion
True or False: Direct current reverses direction at regular intervals. - Answers False
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. - Answers 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) A,B, and C 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. - Answers False.
Kirchhoff's Loop Rule states that the sum of the electric potential differences (voltages) around
any closed loop is zero.

true? Assume that the resistance of each resistor is different. - Answers The sum of the current
through each resistor is equal to the total current of the circuit
True or False: Kirchhoff's Junction Rule states that the sum of the current entering a junction
must equal the sum of the current exiting a junction. - Answers True
