Questions & Step-by-Step Solutions
According to Kirchhoff's Current Law (KCL), what can be said about the currents entering and leaving a junction?
Correct Answer: Total current entering = Total current leaving
Step 1: Understand what a junction is. A junction is a point in an electrical circuit where two or more conductors meet.
Step 2: Know that current is the flow of electric charge. It can enter or leave a junction.
Step 3: According to Kirchhoff's Current Law (KCL), we need to look at the currents at the 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.
Kirchhoff's Current Law (KCL) – KCL states that the sum of currents entering a junction is equal to the sum of currents leaving that junction, reflecting the principle of conservation of electric charge.
