In a schematic, what voltage would be found across l1 to l2?

• A. 120 volts
• B. 240 volts
• C. 480 volts
• D. 60 volts

Answer: (B)

The correct answer is 240 volts, which typically represents the voltage found across two hot conductors in a standard residential or commercial electrical system designed for such configurations. In a typical household electrical system, 120/240 volt configurations are common in which two hot legs or lines are used to provide power. When we measure the voltage between these two lines (l1 and l2), we are essentially measuring the potential difference created by the two separate phases of electrical supply. Since each line carries 120 volts with respect to the neutral, the total voltage between the two lines adds up to 240 volts. Understanding this concept is crucial, especially in applications involving larger appliances or equipment that require higher voltage for operation, typically in the 240-volt range. This knowledge is fundamental when working with electrical systems and ensures safety and proper functioning within electrical installations.
