A) uses circuits symbols to draw a series circuit with a battery connecting wires into lightbulbs
b) draw a parallel circuits, using the same components as a
c) describe the difference in current flowing in the two circuits a and b
d) what will happen to the brightness of the bulbs in circuit a if one of the boats is unscrewed
e) what will happen to the brightness of the bulbs in circuit b if one of the light bulbs is unscrewed
a)
[Battery] (+) --- [Wire] --- [Lightbulb] --- [Wire] --- [Lightbulb] --- [Wire] --- (-)
b)

c) In a series circuit, the current is the same through all components. In a parallel circuit, the current is divided among the branches, with some going through each component.
d) If one of the light bulbs in circuit a is unscrewed, the other light bulb will not light up because the circuit is broken.
e) If one of the light bulbs in circuit b is unscrewed, the other light bulb(s) will still light up because the circuit branches allow current to continue flowing through the other branches/components. However, the remaining bulb(s) will receive more current and may become brighter.
A) To draw a series circuit with a battery connecting wires into lightbulbs, follow these steps:
1. Draw a straight horizontal line to represent the battery.
2. Draw a small circle on the left side of the battery line, indicating the positive terminal (+) of the battery.
3. Draw another small circle on the right side of the battery line, indicating the negative terminal (-) of the battery.
4. Connect a straight line from the positive terminal of the battery to the first lightbulb.
5. Draw a box with a squiggly line inside it to represent the lightbulb.
6. Connect a straight line from the first lightbulb to the second lightbulb.
7. Repeat step 5 to draw the second lightbulb.
8. Connect a straight line from the second lightbulb to the negative terminal of the battery.
B) To draw a parallel circuit using the same components, follow these steps:
1. Draw a straight horizontal line to represent the battery.
2. Draw a small circle on the left side of the battery line, indicating the positive terminal (+) of the battery.
3. Draw another small circle on the right side of the battery line, indicating the negative terminal (-) of the battery.
4. Connect two straight lines from the positive terminal of the battery, each going to a separate lightbulb.
5. Draw a box with a squiggly line inside it to represent the first lightbulb at the end of one of the lines.
6. Draw a box with a squiggly line inside it to represent the second lightbulb at the end of the other line.
7. Connect two straight lines from each lightbulb, all converging and connecting to the negative terminal of the battery.
C) In a series circuit, the current flowing through each component is the same. However, in a parallel circuit, the total current gets divided among the branches, and the current flowing through each component can vary.
D) If one of the bulbs in circuit A is unscrewed, the circuit will be interrupted, and the other bulb will not light up. The brightness of the remaining bulb will be zero.
E) In a parallel circuit, if one of the light bulbs is unscrewed, the circuit will not be interrupted. The other light bulb(s) will continue to function, and their brightness will not be affected.
