parrallel
-
-
The total amount of current flowing into the junction, or split, is equal to the total current flowing out.
-
two lamps in a parrallel
-
If one lamp breaks, the other lamp will still light.

-
For a parallel circuit, the sum of all the current in every branch is equal to the current from the electrical supply.
charge and current
-
-
The electrons are free to move from one ion to another and a net flow of these electrons in one direction is an electric current.
A source of energy, such as a cell or battery, is required to make the free electrons move in one direction.
charge
Electrons are negatively charged particles and they transfer electrical energy from a cell, through conducting wires, as an electric current.
Charge is measured in coulombs, C.
-
In other words, it takes 6,250,000,000,000,000,000 electrons to make up 1 coulomb of charge.

series
Components that are connected one after another on the same loop of the circuit are connected in series.
two lamps in a series
-
If one lamp breaks, the other lamp will not light.
Series circuits are useful if you want a warning that one of the components in the circuit has failed.
For example, a circuit breaker or fuse must be connected in series in order for it to work.
