Conclusion Questions
1.
State two rules for the voltage and current in a series circuit.
The current flowing through every series component is equal.
The total resistance (RT) is equal to the sum of all of the resistances (i.e., R1 + R2 + R3).
2.
State two rules for the
voltage and current in a parallel circuit.
The voltage across every parallel component is equal.
The total resistance (RT) is equal to the reciprocal of the sum of the reciprocal:
The sum of all of the currents in each branch (IR1 + IR2 + IR3) is equal t
o the total current
(IT). This is called Kirchhoff’s Current Law.
3.
If you remove a single bulb from an inexpensive string of Christmas tree lights, all of
the lights in the entire string will go off. Are the bulbs connected in series or parallel?
Explain.
Series circuit because they depend on each other to carry the flow of
electricity, If one component goes out, so do all the others.
