Exploring Series and Parallel Circuits

What does a zigzag line represent in a schematic diagram?

• A switch

• A battery

• A resistor

• A wire

What symbol is used to represent a battery in a schematic diagram?

• A loop inside a circle

• A simple circle

• A zigzag line

• A set of parallel lines

In a series circuit, if one component fails, what happens to the flow of electricity?

• It reverses direction

• It only affects the failed component

• It stops completely

• It continues through other paths

How are components connected in a parallel circuit?

• In multiple paths

• In a closed loop

• In a single path

• In an alternating pattern

What is the primary factor that determines whether resistors are in series or parallel?

• Voltage of the battery

• Type of resistors used

• Whether the current divides

• Physical layout of the resistors

What is the effect of adding more bulbs in series on the circuit's total resistance?

• It increases

• It becomes zero

• It stays the same

• It decreases

What happens to the brightness of bulbs in a series circuit when more bulbs are added?

• They glow dimmer

• They glow brighter

• Only the last bulb glows

• Brightness does not change

In a parallel circuit, if one bulb burns out, what happens to the other bulbs?

• All bulbs go out

• Remaining bulbs stay lit

• Remaining bulbs glow dimmer

• Remaining bulbs glow brighter

What happens to the overall resistance when more bulbs are added in parallel?

• It increases

• It decreases

• It stays the same

• It fluctuates

How does adding more paths in a parallel circuit affect the current flow?

• Decreases current flow

• Increases current flow

• No change in current flow

• Stops current flow
