Which of the symbols below means battery?

• 
• 
• 
• 

What would the voltage output be of the batteries shown in the image if they are all 1.5 volt batteries?

• 4.5 volts

• 1.5 volts

• There would be no voltage output

• 12 volts

Look at the image. Which statement below is correct?

• Based on the voltage of the battery, bulb 'C' should not be lit.

• The voltage is shared equally amongst all three of the light bulbs

• The voltage reduces across each of the bulbs.

• Current is increased as it travels through the bulbs

If the resistance of an electrical circuit is increased, what will happen to the current assuming the voltage remains the same?

• The current will remain the same

• The current will increase

• There will be no difference to the current

• The current will decrease

Using Ohm's law calculate the voltage of the circuit shown.

• 1 000 volts

• 40 volts

• 0.25 volts

• 10 volts

What is the name of the item shown?

• Pin board

• Circuit board

• Temporary board (temp board)

• Breadboard

In what way is a light emitting diode the same as a standard diode?

• Both emit light

• Current can only flow in one direction

• Current flows from the cathode to the anode in both

• Current is saved and builds up making the light brighter

Which of the statements below best describe Arduino?

• A selection of micro controller boards

• An easy to use computer communication format

• A basic coding language

• An open-source electronics platform based on easy-to-use hardware and software
