Questions & Step-by-Step Solutions
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.
