Question 1
Network TheoryKirchhoff Laws

Kirchhoff’s Current Law states that at any node?

  • AThe algebraic sum of currents is zero
  • BThe algebraic sum of voltages is always one
  • CPower is always zero
  • DResistance is always maximum
Report an error
Correct Answer: A. The algebraic sum of currents is zero
Explanation: KCL follows conservation of charge: the algebraic sum of currents entering and leaving a node is zero.
Reference: Standard network theory: kirchhoff laws
Question 2
Network TheoryKirchhoff Laws

Kirchhoff’s Voltage Law states that around any closed loop?

  • AThe algebraic sum of currents is zero
  • BThe algebraic sum of voltages is zero
  • CAll resistances are equal
  • DAll branch currents are equal
Report an error
Correct Answer: B. The algebraic sum of voltages is zero
Explanation: KVL follows conservation of energy: the algebraic sum of voltage rises and drops around a closed loop is zero.
