Unformatted text preview: rcuit, several such loops can be found. The algebraic sum of voltages equals zero for any closed path (loop) in an electric circuit. In other words, net voltage rise (or net voltage fall) around a loop is equal to zero. Net voltage rise is obtained by adding the voltage rises and subtracting the voltage falls. A convenient convention is to add the voltage of the element if we first encounter the positive polarity mark and to subtract the voltage for the element if we first encounter the negative polarity mark. Travelling from positive terminal to the negative terminal implies voltage is dropping across the element. Travelling from the negative terminal to the positive terminal implies voltage is increasing along the path. The voltages across each element in the closed path would be the energy lost or gained per unit charge travelling along the path. As we come back to the same point, the charge should not have gained or lost ay energy as otherwise it would violate the energy conservation principle. 24 EE10...
