In resistive loads, the current is ________ with the voltage.

• A. Lagging
• B. Leading
• C. Out of phase
• D. In phase

Answer: (D)

In resistive loads, the current is in phase with the voltage, which means that the peaks and zero crossings of the current waveform occur simultaneously with those of the voltage waveform. This characteristic is due to the nature of resistive components, where the voltage drop across the resistor is directly proportional to the current flowing through it, following Ohm's law (V = IR). When the voltage across a resistive load increases, the current increases proportionally at the same instant. Conversely, when the voltage decreases, the current decreases equally, without any delay or phase shift. This in-phase relationship is crucial in understanding how resistive circuits function, as it simplifies calculations related to power, energy consumption, and circuit behavior. Understanding that current and voltage are in phase in resistive loads helps in the application of electrical principles in various scenarios, including troubleshooting and system design within the entertainment technology field.
