Which statement best describes Kirchhoff’s voltage law for the circuit as shown in the figure below?
A) The total voltage across all elements in a closed loop is equal to the sum of the individual voltages.
B) The total current entering a junction is equal to the total current leaving the junction.
C) The sum of the currents flowing into and out of a node is zero.
D) The sum of the voltages in any closed loop is equal to the sum of the product of the currents and resistances.
The correct answer is D)
Explanation:
Kirchhoff’s Voltage Law (KVL) states that the algebraic sum of the voltages in any closed loop or mesh of a circuit is equal to the sum of the product of the currents and the resistances in that loop. In other words, the total voltage around a closed loop is equal to the total voltage drop due to the components (resistors, capacitors, inductors, etc.) in that loop.
