1. How do series and parallel circuits differ in terms of the total current?

a. In series circuit, current is dissimilar at different points while in parallel circuit, the current is constant at all points in the circuit.
b. In series circuit, the current is the same at all points in the circuit while in parallel circuit, current is not similar at different points.
c. In series circuit, current changes at every point in the circuit while in parallel circuit, the first path has always the least current among the other paths.
d. In series circuit, current is variable at every point in the circuit while in parallel circuit, the first path has always the highest current among the other paths.

2. How do series and parallel circuits differ in terms of the resistance?

a. In series circuit, the resistance increases as more loads are added while in parallel circuit the resistance decreases as more loads are added.
b. In series circuit, the resistance decreases as more loads are added while in parallel circuit the resistance increases as more loads are added.
c. Total resistance is always constant with increasing load in a series circuit while the total resistance increases with increasing load in a parallel circuit.
d. Total resistance is always less than the individual resistance in a series circuit while the total resistance is always greater than the individual resistance in parallel circuit.

3. How do series and parallel circuits differ in voltage?

a. In series circuit, the voltage is the same between the loads in the circuit while in parallel circuit, the voltage is different in every individual path.
b. In series circuit, the voltage is divided between the loads in the circuit while in parallel circuit, each individual path in the circuit has the same voltage.
c. In series circuit, the voltage is increasing as the load increases while in parallel circuit it has a total voltage that equals to the sum of the voltages across each load.
d. In series circuit, there is only one voltage which is equal to a voltage source while in parallel circuit the voltage source is equal to the sum of all the voltage in each load.

4. What happens when one light is not working in a parallel circuit? *

a. Nothing will happen.
b. All the lights will not work
c. Half of the lights will not work.
d. The remaining lights will still work.

5. What type of connection is involved when only one lightbulb blows out, then an entire string of decorative lights goes out?

a. series with one current pathway
b. parallel with one current pathway
c. series with multiple current pathways
d. parallel with multiple current pathways
