Electric Current

Electric current is a flow of charge.
Current is measured in Amperes (Amps)
Charge is measured in Coulombs

Multiple Choice

Current is measured in:

Amperes (A)

Coulombs (C)

Fill in the Blanks

Current is the flow of

Type answer...

Multiple Choice

Charge is measured in:

Amperes (A)

Coulombs (C)

How does current flow in a circuit?

To make a charge flow around a circuit there has to be something providing a potential difference (push), like a battery.
The potential difference is also known as the volts/voltage (V)

Multiple Choice

Which part of the circuit provides the push (potential difference)?

The wire

The battery

The bulb

Batteries provide the potential difference (voltage/push) to a circuit.

Multiple Choice

Current is measured in

Amperes (A)

Coulombs (C)

Volts (V)

Multiple Choice

Potential difference is measured in

Amperes (A)

Coulombs (C)

Volts (V)

Resistance

Resistance is anything that slows down the flow of charge.
Its units are Ohms, Ω
If the resistance of a circuit increases, a smaller current will flow

Multiple Choice

What is resistance?

Anything that increases the flow of current

Anything that decreases the flow of current

Multiple Choice

What are the units for resistance?

Amperes (A)

Volts (V)

Ohms

Fill in the Blanks

Current is the flow of

Multiple Choice

Current is measured in:

Amperes (A)

Coulombs (C)

Multiple Choice

Potential difference is measured in

Amperes (A)

Coulombs (C)

Volts (V)

Multiple Choice

Which part of the circuit provides the push (potential difference)?

The wire

The battery

The bulb

How fast charge flows - Equation Units

Q= Charge flow - Coulombs (C)
I = Current - Amps (A)
T= Time - Seconds (S)

Multiple Choice

What equation would you use to measure current (I)?

Q $\div$ T

I $\div$ Q

T $\times$ Q

I $\times$ T

Multiple Choice

What equation would you use to measure Charge (Q)?

Q $\div$ T

I $\div$ Q

T $\times$ Q

I $\times$ T

Multiple Choice

What equation would you use to measure Time (T)?

Q $\div$ T

Q $\div$ I

T $\times$ Q

I $\times$ T
