Questions & Step-by-Step Solutions
According to Kirchhoff's Voltage Law, the sum of the potential differences around any closed loop in a circuit is equal to what?
Correct Answer: Zero
Step 1: Understand that Kirchhoff's Voltage Law (KVL) deals with electrical circuits.
Step 2: Recognize that a closed loop in a circuit means you start and end at the same point.
Step 3: Identify that 'potential differences' refer to the voltage across components in the circuit.
Step 4: Know that 'electromotive forces' (emf) are the voltages provided by sources like batteries.
Step 5: KVL states that if you add up all the voltages (both positive and negative) around the loop, the total will equal zero.
Kirchhoff's Voltage Law – This law states that the sum of the electromotive forces (emf) and potential differences (voltage drops) in any closed loop of a circuit must equal zero.
