- The same current flows through all components
- The same voltage is applied across all components
- The total resistance is equal to the highest resistor value
- Components are connected sequentially
Answer: B
Explanation: In a parallel circuit, each component has the same voltage across it, although the current can vary for each branch.
Question 8: Which component limits the current in a circuit and provides overcurrent protection?
- Resistor
- Capacitor
- Circuit breaker
- Transformer
Answer: C
Explanation: Circuit breakers protect electrical circuits by interrupting overcurrent flow, thereby preventing damage and potential hazards.
