Which of the following is true regarding a series circuit? - ANS The current flow is the
same through all resistors.
Which of the following is true regarding a parallel circuit? - ANS It has more than one
path for current flow.
Which of the following is true regarding a series-parallel circuit? - ANS If a circuit is
reduced to an equivalent series circuit, the total resistance is found by adding the loads.

current of 30A. Branch R1 takes 15A. What s the current I2 in branch R2? - ANS 15A
Who stated that the current entering a point must equal the total current leaving that
point? - ANS kirchhoff

the value of E3 must be__________? - ANS 3V
True or False? You can use ohm's law to find the value of each branch current in a
parallel circuit. - ANS True
