According to Kirchhoff's Current Law at a junction, which statement is correct?
AThe sum of currents entering a junction equals the sum of currents leaving it.
BThe algebraic sum of voltages at a junction is zero.
CCurrent is the same through every branch connected to the junction.
DThe product of current and resistance is conserved at a junction.
Answer & Solution
Correct answer: A. The sum of currents entering a junction equals the sum of currents leaving it.
Kirchhoff's Current Law states that charge is conserved at a junction, so total current entering equals total current leaving. The other options either describe voltage behavior or make incorrect claims about branch currents.
