Power is conserved
Current is constant throughout the circuit
Questions & Step-by-Step Solutions
According to Kirchhoff's Current Law (KCL), what must be true at any junction in a circuit?
Step 1: Understand what a junction is. A junction is a point in a circuit where two or more wires meet.
Step 2: Know that current is the flow of electric charge. It can enter or leave the junction.
Step 3: According to Kirchhoff's Current Law (KCL), we need to look at the currents going into and out of 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 coming into the junction, it should equal the sum of 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.
