Abstract

A detection device for detecting a line quality of an electric circuit includes two electrical connection members inserted into a socket and connected to two power lines, a load resistor, a switching member, a displaying module, and a control module. An end of the load resistor is connected to one of the electrical connection members, and another end thereof is connected to a first end of the switching member. A second end of the switching member is connected to the other electrical connection member. The control module controls the switching member to cut off when in a detection mode, and detects a peak voltage in a voltage waveform and records as a maximum open-circuit voltage, and controls the switching member to conduct and detects the peak voltage of the voltage waveform and records as a load voltage and calculates a load current. A line resistance value is calculated based on the maximum open-circuit voltage, the load voltage, and the load current. A message is correspondingly displayed via the displaying module.
