Solving Circuit Diagrams
1. State the two mathematical equations for series circuits that explain how current and
voltage is related to the total current and voltage.
a) VT = __________________________
b) IT = ___________________________
2. State the two mathematical equations for parallel circuits that explain how current and
voltage is related to the total current and voltage.
c) VT = __________________________
d) IT = ___________________________
3. Electricity behaves differently in series and parallel circuits. It is your job to solve these
circuit diagrams by filling out all of the blanks beside each diagram. Draw an arrow to
show the direction of electron flow.
