According to Kirchhoff's Current Law (KCL), what can be said about the current entering a junction?
  1. It must equal the current leaving the junction.
  2. It can be greater than the current leaving.
  3. It can be less than the current leaving.
  4. It has no relation to the current leaving.

Questions & Step-by-Step Solutions

According to Kirchhoff's Current Law (KCL), what can be said about the current entering a 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, 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.
  • Kirchhoff's Current Law (KCL) – KCL states that the sum of currents entering a junction must equal the sum of currents leaving that junction.
