Questions & Step-by-Step Solutions

What is the total voltage in a closed loop according to Kirchhoff's Voltage Law (KVL)?
  • Step 1: Understand that Kirchhoff's Voltage Law (KVL) deals with electrical circuits.
  • Step 2: Know that a closed loop in a circuit means you start and end at the same point without any breaks.
  • Step 3: Remember that voltage is a measure of electrical potential difference.
  • Step 4: KVL states that if you add up all the voltages (both positive and negative) around the closed 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.
