A parallel circuit is one of the fundamental types of electrical circuits found in various electronic devices and appliances. It consists of multiple paths for electric current to flow through, ...

A parallel circuit is one of the fundamental electrical circuits wherein various components, such as resistors, are arranged with their heads connected together, and their tails connected together.

The two resistors have the same current through them. The potential difference across them will be different if they have different resistances. The total resistance (\(R_{T}\)) for this circuit is ...

The flashing is thanks to LEDs with a built-in, integrated flashing circuit and the nasty noise comes from a piezoelectric buzzer — both are available from electronics stores that sell ordinary LEDs.

If there are no branches then it's a series circuit. If there are branches it's a parallel circuit. In a television series, you get several episodes, one after the other. A series circuit is similar.
