Questions & Step-by-Step Solutions
According to Kirchhoff's Voltage Law, the sum of the potential differences around any closed loop in a circuit must equal what?
Step 1: Understand that a closed loop in a circuit means you start and end at the same point.
Step 2: Recognize that potential difference is another term for voltage, which is the energy per unit charge.
Step 3: Realize that Kirchhoff's Voltage Law (KVL) says that if you add up all the voltages in that closed loop, they will balance out.
Step 4: This means that the total voltage gained (like from batteries) minus the total voltage lost (like across resistors) equals zero.
Step 5: Therefore, the sum of the voltages around the loop must equal zero.
Kirchhoff's Voltage Law – The principle that the total voltage around a closed loop in a circuit must equal zero, accounting for all voltage rises and drops.
