Answer 1

A circuit is a complete path along which electricity flows. The essential elements in a basic electrical circuit consist of: A source, load, and ground. Electricity cannot flow without a power source (battery), and a load (bulb or resistor-electrical device/ component) and a closed conductive path (wires connecting it). Electrical circuits consist of wires, wire connectors, switches, circuit protection devices, relays, electrical loads, and grounds. The circuit shown below has a power source, fuse, switch, a lamp and wires connecting each into a loop. When the connection is complete, current flows from the positive terminal of the battery through the circuit to the negative terminal of the battery.
