In the April 10 issue of The News, several readers noted that some of the wiring diagrams accompanying the article on “Electricity 101” were flawed. We salute their sharp eyes, and hope their letters help clear up any confusion this seemingly basic article may have caused.
From a reader at Tringale Electric, Lexington, MA: “Concerning the diagrams, Figure 2 needs to be corrected in both A and B voltage drops due to the fact that the light, if it is a light, could not be arrived at these voltage drops. Assuming this is a light, I therefore question the values of the voltage in both diagrams. The only way these values could be arrived at would be to replace the light as shown with a single-pole switch.
