Questions & Step-by-Step Solutions
What does KCL state about currents at a junction?
Correct Answer: KCL states that total current entering a junction = total current leaving the junction.
Step 1: Understand what a junction is. A junction is a point where two or more electrical paths meet.
Step 2: Know what current is. Current is the flow of electric charge in a circuit.
Step 3: Recognize that KCL is a rule about how current behaves at a junction.
Step 4: KCL states that the total amount of current flowing into the junction must be equal to the total amount of current flowing out of the junction.
Step 5: This means if you add up all the currents going into the junction, it should equal the sum of all the currents going out.
