Question 241Electricity & Electronics - QMED

The correct answer is D) they all have the same current passing through them. In a DC series circuit, all the connecting conductors are part of the same unbroken path for the current to flow. Since the current is the same at every point in a series circuit, the current passing through each connecting conductor will be the same. This is a fundamental principle of series circuits. The other options are incorrect because: A) the power expended may vary if the resistances are different, B) the resistances of the conductors may differ, and C) the voltage drops across each conductor will depend on their individual resistances.
