- Q11. Emiel bought a new air conditioning unit. He called someone to install the unit in his room. He was told by the electrician that he would need a circuit breaker aside from other electrical materials. Why would he need a circuit breaker?Circuit breaker acts as a remote control to turn on and off the unit.Circuit breaker allows the appliance to save more energy.Circuit breaker does not possess any significant function in electricity.Circuit breaker offers protection by tripping and cutting off the supply to load in case of fault.120s

- Q88. Which of the following best describes voltage?A. flow of electrons in a circuitD. the potential difference between two points in a circuitB. the amount of energy that flows in a circuitC. the opposing force relative to the flow of electrons120s
- Q99. Ezra received an appliance from her cousin who lives in America. After checking the appliance, she noticed that the value of voltage is different from her outlets. The voltage of the appliance is 120 volts while her outlet is 220 volts. What does it mean?All of theseThe appliance requires less amount of voltageThe appliance and outlet is not compatibleIt is dangerous to plug the 120-volt appliance to the 220-volt outlet120s

- Q1212. According to Ohm’s law, the current through a conductor between two points is directly proportional to the voltage across the two point. What happens to the current when the voltage increases?The current decreases.The current will go infinite.The current stays the sameThe current increases.120s
- Q1313. Which of the following best describes the Ohm’s Law?It states that the current is inversely proportional to voltage and directly proportional to resistance.It states that the current is directly proportional to voltage and inversely proportional to resistance.It states that the current is directly proportional to both voltage and resistance.It states that the current is inversely proportional to both voltage and resistance.120s
- Q1414. A current of 1.5 A is passing through a conductor with a 10.5 V power source. What is the resistance of the circuit?3 Ω9 Ω7 Ω5 Ω120s
- Q1515. Juliet loves to read novels at night. When reading, Juliet wants to have an ambient light. So it’s her practice to dim her lampshade by adjusting the knob on it. Which factor was changed to dim the light of the lampshade?ResistanceVoltageCurrentBulb120s
