Answer the following statement(s) true (T) or false (F)
1. Since the current flow through a series circuit is the same at all points in the circuit, the voltage drop across any particular resistance is equal to the total circuit current plus the value of that resistor. 2. In discussing the voltage distribution of a circuit, it is not good enough to merely refer to the magnitude of the voltages, because equal consideration should be given to the polarity of the voltages. 3. The concept of a reference point is important in describing not only polarity markings but voltage levels as well. 4. In the series-aiding method of connecting voltage sources, the positive pole of one source always connects with the positive pole of another source. 5. When two voltage sources are interconnected with identical poles, such connections are known as series-opposing.
