...account, the sum of the potential differences around any closed circuit or network is zero. This is illustrated in Figure 10, which is a screenshot taken from an online circuit simulation package called Multisim Live. Here, starting with the battery, the voltages around the circuit are 6.0 V − 1.0 V − 3.0 V − 2.0 V = 0 V. [Described image] Figure 10 Illustration of...
