Q1
According to Kirchhoff's Current Law (KCL), what must be true at any junction in an electrical circuit?
The sum of currents entering equals the sum of currents leaving
The voltage is constant
The total resistance is zero
Power is conserved
KCL states that the total current entering a junction must equal the total current leaving that junction.

Q
Q: According to Kirchhoff's Current Law (KCL), what must be true at any junction in an electrical circuit?
Solution: KCL states that the total current entering a junction must equal the total current leaving that junction.
Steps: 5
Step 1: Understand what a junction is. A junction is a point in an electrical circuit where two or more wires meet.
Step 2: Know what current is. Current is the flow of electric charge, measured in amperes (A).
Step 3: Recognize that KCL is a rule about current 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.
