Best Answer

Electrical currents require a circuit to flow. If the circuit is broken, then the electrical current will not flow. A switch is a prime example of this principle. When a switch is off, the circuit is broken. However, when it is turned, the circuit is completed and allows for the electrical current to flow through the appliance.

In automotive electrical circuits current is considered to flow from where to where?

In an automotive electrical circuit, current is considered to flow from negative to positive in that circuit. Electrons leave the negative terminal of the battery, flow through any complete circuits, and return to the positive terminal of the battery.


Advantage of current limiting?

Current limiting is the practice in electrical or electronic circuits of imposing an upper limit on the current. The simplest form of current limiting in mains is fuse.
