[amp_mcq option1=”Current and voltages are in phase through a resistor” option2=”Current leads the voltage through a resistor” option3=”Current lags the voltage through a resistor” option4=”All of the above E. None of the above” correct=”option1″]
The correct answer is: A. Current and voltages are in phase through a resistor.
In a resistor, the current and voltage are in phase. This means that they reach their maximum and minimum values at the same time. This is because the resistance of a resistor does not change with the frequency of the AC signal.
Option B is incorrect because the current does not lead the voltage through a resistor.
Option C is incorrect because the current does not lag the voltage through a resistor.
Option D is incorrect because only option A is correct.
Option E is incorrect because option A is correct.
