To open and close the circuit.
If you get sparking in an electrical switch there is a loose connection or short in the circuit. The switch should be repaired or replaced.
A transistor is a semiconductor(like many) that amplifies and switches electrical signals(electronic switch) in a circuit, it is used inside a circuit which requires switching without been manually operated.
The drawing of an electrical circuit is called a circuit diagram, or schematic diagram. It is a graphical representation of the electrical components and their interconnections in a circuit. It uses standardized symbols to represent different components such as resistors, capacitors, transistors, switches, and wires. The lines connecting the symbols in the diagram indicate the flow of electrical current through the circuit. Circuit diagrams are used to design, troubleshoot, and repair electrical systems, and can be found in technical manuals, books and online resources.
cutting off or isolating an electrical circuit
No, an electrical approved switch is used to break an electrical circuit.
In electrical engineering there are many types of symbols used to notate devices. These include symbols for polarity, switches, diodes, and batteries.
Quite often, the word "circuit" is used for an electrical circuit. In that case, the energy is electrical energy.
In an electrical system, essentially any conductive substance could be used to form a switch. At the integrated circuit level, it would be a partial conductor.
