It is used to measure the voltage, resistance and current of a circuit. It connected in parallel or series with the circuit depending on what to measure.

It is used to measure the diameter of wires/conductors in circular mils. It can measure small and big sizes of wires and cables.

A pocket-sized tool used to test the line wire or circuit if there is current in it.

A measuring tool used to measure the length of an object in centimeter and inches and is used for drawing straight lines.

A unit of measurement which describes the amount of electric current passing a certain point at a time.

A unit of measurement of electrical pressure or voltage

Is a measure of the opposition to current flow in an electrical circuit.

The unit of measurement used to express resistance.

It states that the voltage or potential difference between two points is directly proportional to the current or electricity passing through the resistance, and directly proportional to the resistance of the circuit.
