Question: In an AC circuit, what is the relationship between voltage and current in a purely resistive load?

Options:

Correct Answer: Voltage and current are in phase

Solution:

In a purely resistive AC circuit, the voltage and current are in phase, meaning they reach their maximum and minimum values at the same time.

In an AC circuit, what is the relationship between voltage and current in a purely resistive load?

In an AC circuit, what is the relationship between voltage and current in a purely resistive load?

Step 1: Understand what an AC circuit is. AC stands for alternating current, which means the current changes direction periodically.
Step 2: Know what a purely resistive load is. This means the load only has resistance and does not have any inductance or capacitance.
Step 3: Learn about voltage and current. Voltage is the electrical force that pushes the current through the circuit, while current is the flow of electric charge.
Step 4: In a purely resistive load, the voltage and current change together. When the voltage goes up, the current goes up at the same time.
Step 5: This relationship is called 'in phase.' It means that both voltage and current reach their highest and lowest points at the same time.

Phase Relationship – In a purely resistive load, voltage and current waveforms reach their peak values simultaneously, indicating they are in phase.
AC Circuit Behavior – Understanding how resistive loads behave in AC circuits is crucial for analyzing circuit performance.
