Introduction To Electricity Flashcards
1
Q
What does a cell do?
A
Pushes current around a circuit
2
Q
What is a circuit?
A
A cell, a wire and a bulb
3
Q
Charge symbol and measurement?
A
Q, C (coulombs)
4
Q
Current symbol and measurement
A
I, A (Amps)
5
Q
What is potential difference
A
For electrical charge to flow through a closed circuit, the circuit must include a source of potential difference
6
Q
What is the voltage at each point in the circuit in a closed circuit and why
A
Maximum electric potential energy
Energy is transferred
From the charge to the components
7
Q
What is the colour of the bulb when energy goes through it
A
Red, eventually white
8
Q
What is the relationship between the resistance and current?
A
Inversely proportional
9
Q
What is the relationship between p.d. And current
A
Directly proportional
