NEET Physics AC Voltage MCQ Question
In an alternating current (AC) circuit, which quantity must be considered when adding voltages across different elements?
Their phases
Their magnitudes only
Their frequencies
Their resistances
Correct Answer
Detailed Explanation
In an AC circuit, when adding voltages across different elements, it is crucial to consider their phases properly, as indicated in the NCERT context. This means that the total voltage across a combination is not simply the sum of the voltages but must account for their phase relationships.
