Checking For Electrical Current Traveling Through A Wire . Hold the tip of the voltage tester against the side of the electrical cord. Before you check whether a cable is live switch the power off first.
Current Flow Overview How Electricity Travels Through Wires from greencoast.org
To test a wire or other piece of electrical equipment, you use the two probes attached to the device: Expose the wires or fuse ends. Pass it near your phones compass and see if you can get the “needle” to deflect.
Current Flow Overview How Electricity Travels Through Wires
If it displays a number, this are the ohm resistance reading — the lower the number, the better. Pick up a receptacle tester on amazon. Plug 1 part of the circuit breaker finder into the outlet you’d like to test, then drag the other part of the circuit breaker finder down the circuit breaker. Although different types of multimeters can have more or fewer functions, you can safely assume that your multimeter is equipped to test a wire for power.

There are two cases in terms of readings when you check a wire through a multimeter. A quick reminder on the test process: One red (positive) and the other black (negative). Remember that a voltage is always a potential between two points. Before the positive and negative wires are attached it is important that the power is switched off completely.
