Electricity Flashcards
1
Q
What is electric current
A
Electric current is a flow of electrical charge
2
Q
series circuit
A
A series circuit has the same current through each component
The total potential difference of the power is supply is shared between the components
3
Q
Parallel circuits
A
The potential difference across each component is the same
The total current through the whole circuit is the sum of the currents through the separate components
4
Q
3 types of cables
A
Earth wire(green yellow striped-straight up)
Live wire(brown wire-bottom right)
Neutral wire(Blue wire-bottom left)
5
Q
Transformers
A
The transformers increase the potential difference of the electricity
