Determine the voltage across R2 in the figure below, if the source is 6V, the Zener is 5.2V, R1= 10k ohms, and R2= 10k ohms.
Theory The defining characteristic of a series circuit is that there is only one path for electrons to flow. The principle to understand is that the amount of current is the same through any component in the circuit. This is because there is only one path for electrons to flow in a series circuit.
