Electrons need to be able to flow from each part of the circuit to the next, and they don’t flow easily through air. This is why wires are used. They have a smaller resistance than air, and so the electrons can flow smoothly.
Yes.
Yes, the current in both circuits is the same when they are connected in parallel.
They are not. They are connected differently, and the voltages and currents behave in different ways.
that is called a perfect circuit
The point where wires interconnect with other wires is known as a "junction". In your panel the circuit breakers are connected to the buss, each circuit breaker feeds a different circuit. Different circuits are not connected together.
When you have multiple circuits connected to a site, the entire circuit is known as a "distribution circuit" or a "feeder circuit." These circuits distribute electricity from a central source to various points of use within the site.
First, circuits have devices that are run by electrical energy. Second, a circuits has a source of electrical energy. Third, electrical circuits are connected by conducting.
There are two circuits on the battery and motor. One wire is take which have four ends. The wire is connected on the desired circuits.
Typically they are both. Most are paralleled from the breaker and then serial from each power switch.
virtual circuit
Parallel for main circuits and series parallel for lighting circuits.
Voltmeters are connected to simple series circuits the same way they are connected to any circuit. They are connected in parallel with the portion of the circuit for which you wish to measure the voltage drop.
