Two lamps connected in series with an open switch and a cell The circuit diagram shows a circuit with two lamps connected in series. If one lamp breaks, the other lamp will not light. The current is ...

When resistors are connected in series, the current through each resistor is the same. In other words, the current is the same at all points in a series circuit. When resistors are connected in series ...

Last month's column covered the behavior of electrical components connected in series and demonstrated that when a voltage is applied across a series circuit, the current through each component is the ...

The topic of electricity often poses difficulties for many secondary school students in physics lessons. Researchers have now developed and empirically evaluated a new, intuitive curriculum as part of ...

Our last article covered voltage troubleshooting in series with power-consuming devices (motors) [“Electrical Troubleshooting,” March 5, p. 16]. The article differentiated between an open and a closed ...

This answer is based on the 2017 NEC. A. Separate raceways or cables containing parallel conductors must have the same electrical characteristics [310.10(H)(3)], as shown in the Figure. If one set of ...
