Resistance

 1 Resistences

Electrical resistance is an opposition of current of an object flowing through it. We use resistences to safe our circuit and wires.

2 Soldering Iron

Soldering iron is an instrument made up of a metal which gets heat up and transfer heat to electrical components like wires.

3 Connecting Wires

Connecting wires permits current to transfer from one point to another in the circuit because electrical need a medium to move between two points.
