Questions & Step-by-Step Solutions
According to Kirchhoff's Current Law (KCL), what must be true at a junction?
Step 1: Understand what a junction is. A junction is a point where two or more electrical paths meet.
Step 2: Know that current is the flow of electric charge. It can enter or leave a junction.
Step 3: Remember 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 equal the total amount of current flowing out.
Step 5: This means if you add up all the currents coming into the junction, it should be the same as adding up all the currents going out.
Kirchhoff's Current Law (KCL) – KCL states that the total current entering a junction in an electrical circuit must equal the total current leaving that junction.
