P4.2 Electricity (Charge Flow)

How must the wires always be in your circuit diagram?

• drawn with a pencil
• straight lines
• parallel
• drawn with thick lines

For a circuit to work the circuit must be…

• closed
• open
• on
• charged up

Electric current is a flow of…

• volts
• water
• electrical charge
• resistance

Current is measured in…

• volts, V
• coulombs, C
• ohms, Ω
• amperes, A

Charge is measured in…

• volts, V
• coulombs, C
• ohms, Ω
• amperes, A

Electrical charge will only flow (around a completed circuit) if there is a…

• potential difference
• lightning
• time
• fuse

Potential difference is the same as…

• current
• voltage
• resistance
• charge

Resistance is anything that slows down the flow of…

• current
• voltage
• resistance
• charge

In a single, closed loop (circuit) the current…

• is different on each branch
• is the same everywhere
• varies around the circuit
• steps up and down

The size of the current tells you WHAT about the charge flowing?

• how fast

• the size

• 110 V
