Questions & Step-by-Step Solutions
In a series circuit, how does the total current relate to the individual branch currents according to KCL?
Correct Answer: Total current is equal to the sum of individual branch currents.
Step 1: Understand that a series circuit has only one path for current to flow.
Step 2: Know that Kirchhoff's Current Law (KCL) states that the total current entering a junction equals the total current leaving the junction.
Step 3: In a series circuit, there are no junctions where current splits; therefore, the current is the same throughout the circuit.
Step 4: Since the current is the same, the total current in the circuit is equal to the current in each branch.
Step 5: Conclude that in a series circuit, the total current is equal to the individual branch currents because there is only one path for the current.
