What happens to the current when lamps are connected in series?
- The current stays the same for all lamps. (correct)
- The current increases for each lamp.
- The current decreases for each subsequent lamp.
- The current splits among the lamps equally.
How does the arrangement of lamps in a parallel circuit affect their brightness?
How does the arrangement of lamps in a parallel circuit affect their brightness?
- Lamps will have equal brightness to a single lamp.
- Lamps will be dimmer than a standard lamp. (correct)
- Lamps are brighter than in a series circuit.
- Lamps will not light up at all.
What effect does adding more batteries in series have on the circuit?
What effect does adding more batteries in series have on the circuit?
- It increases the total voltage of the circuit. (correct)
- It has no effect on the circuit’s voltage.
- It reduces the voltage of the circuit.
- It causes the lamps to flicker randomly.

Study Notes
Circuit Analysis - Current
- Water leaks in pipes are analogous to current leaks in electrical circuits. Current is the flow of electricity.
- Wires in circuits are analogous to pipes in water systems. Wires conduct the current.
- Current in parallel circuits splits. The current divides among multiple paths.
- Lamps in parallel circuits are brighter than those in series circuits. The current is split, and each lamp receives a larger portion of the current.
- Current in series circuits stays the same. The current flows through each component in sequence.
- Lamps in series circuits are dimmer than those in parallel circuits. The current is shared by all the lamps.
- Adding or removing dry cells (batteries) in series changes the total current. If more cells are added, the total current increases.
- Adding or removing bulbs in series or parallel changes the brightness of the existing bulbs. Replacing bulbs in parallel will have no effect on the brightness of others.
- Brightness of lamps is related to current flow. A higher current flow leads to brighter lamps
Circuit Diagrams
- Circuit diagrams show the flow of electricity.
- Different connections affect the current flow and brightness.
- Diagrams with bulbs in parallel show current splitting.
- Diagrams with bulbs in series show the current staying constant.
