Questions & Step-by-Step Solutions

What does KVL (Kirchhoff's Voltage Law) state?
Correct Answer: KVL states that the sum of the electrical potential differences around any closed loop is zero.
  • Step 1: Understand that KVL stands for Kirchhoff's Voltage Law.
  • Step 2: Know that KVL deals with electrical circuits.
  • Step 3: Remember that a closed network means a complete loop in the circuit.
  • Step 4: KVL states that if you add up all the voltages in that loop, the total will equal zero.
  • Step 5: This means that the energy supplied by sources (like batteries) is equal to the energy used by components (like resistors) in the loop.
