Question

Recall the use of light bulbs in the lab activity as a crude (qualitative rather than quantitative) tool to understand various circuits. Consider a circuit that includes one light bulb. If the bulb become brighter after some change in the circuit parameters (such as battery voltage and values of resistors), which of the following can be true? (there might be more than one answer)

Recall the use of light bulbs in the lab activity as a crude (qualitative rather than quantitative) tool to understand various circuits. Consider a circuit that includes one light bulb. If the bulb become brighter after some change in the circuit parameters (such as battery voltage and values of resistors), which of the following can be true? (there might be more than one answer) Voltage across the bulb is increased. Current through the bulb is increased. Voltage across the bulb is decreased. Current through the bulb is decreased

Explanation / Answer

voltage is inc
