Electric Circuits Test-2

Kirchhoff’s Voltage Law states that:

• The sum of the voltage drops in a closed loop is equal to the sum of the voltage rises.
• The algebraic sum of the individual currents around a closed loop is zero
• The voltages developed across each element in a series circuit are identical
• The algebraic sum of the resistances is equal to the sum of the voltages

The sum of the potential rises around a closed path will always be equal to the sum of the potential drops. The stated law is called:

• KVL
• KCL
• Ohm’s Law
• None of these

Kirchhoff's Voltage Law works on the principle of:

• Law of conservation of charge
• Law of conservation of energy
• Law of conservation of mass
• None of these
