Circuit Observation and Analysis
What will the student most likely observe in the circuit?
Based on the data provided, what will be the probable outcome for the student's observation in the circuit consisting of a battery, two light bulbs, and a switch?
a. Both light bulb 1 and light bulb 2 will be on
b. Both light bulb 1 and light bulb 2 will be off
c. Light bulb 1 will be off, but light bulb 2 will be on
d. Light bulb 1 will be on, but light bulb 2 will be off
Answer:
Based on the image provided, the student will most likely observe that if the switch is closed, i.e. in the ON position, both light bulb 1 and light bulb 2 will be on. Hence, option B is correct. This is because the circuit is a parallel circuit, which means that the current can flow through each of the light bulbs independently. As long as the battery provides enough voltage, both light bulbs will light up.
When the switch is open, i.e. in the OFF position, both light bulb 1 and light bulb 2 will be off. This is because the circuit is incomplete and there is no complete path for the current to flow through the light bulbs. If there were issues with the battery, such as being dead or not providing sufficient voltage, both light bulbs may not light up or appear dim.
Similarly, if there were complications with one of the light bulbs, like a broken filament, only one of the light bulbs may light up or neither of them may light up. It is crucial to ensure that all components of a circuit are in proper working condition for the circuit to operate as intended.
