Troubleshooting your home's electricity can be easy with the right tool, like a multi-meter that can measure voltage, current, resistance, capacitance, and more. The one I review in this video is also an oscilloscope, which can be handy for measuring signals and frequency of electricity, not just AC or DC voltage.
