electricity

?
what is electricity
a form of energy resulting from the existence of charged particles (such as electrons or protons), either statically as an accumulation of charge or dynamically as a current.
1 of 6
what is potential difference
A potential difference, also called voltage, across an electrical component is needed to make a current flow through it. Cells or batteries often provide the potential difference needed.
2 of 6
what is current
a flow of electricity which results from the ordered directional movement of electrically charged particles.
3 of 6
what is resistance
There is a resistance to the flow of an electric current through most conductors.
4 of 6
how to calculate potential difference
Potential difference (V) = current (I) x resistance (R) V = I x R

what is the difference between series and parallel circuits
In a series circuit, the current through each of the components is the same, and the voltage across the circuit is the sum of the voltages across each component. In a parallel circuit, the voltage across each of the components is the same, and the to
