Which of the following is an advantage of Kirchhoff's law?

• the calculation of unknown voltages and currents become easy

• the simplification of complex closed-loop circuits becomes manageable

• both of these

• none of these

This the basic law that is used for solving an electric circuit.

What does Kirchhoff's Voltage Law (KVL) state?

• 
  The sum of all currents entering a junction must equal zero.

• The total resistance in a series circuit is equal to the sum of individual resistances.

• The sum of all voltages around a closed loop must equal zero.

• 
  The voltage across each component in parallel is different.

What does Kirchhoff's Current Law (KCL) state?

• The sum of all currents entering a junction is equal to the sum of all currents leaving the junction.

• The total resistance in a parallel circuit is equal to the sum of individual resistances.

• The sum of all voltages around a closed loop must equal zero.

• The voltage across each component in series is the same.
