Question
Answer
show Measures how much electricity is flowing around a circuit. Placed in series.  
🗑
amp (A)   show
🗑
atom   show
🗑
show A source of electricity with a low ‘energy’. Cells push electrons round a circuit so each can carry energy [voltage].  
🗑
circuit   show
🗑
component   show
🗑
conductor   show
🗑
earth wire   show
🗑
show The flow of electrons around a circuit from a region of high potential [big bar] to a region of low potential [little bar.  
🗑
show When electricity flows through the body.  
🗑
electrical energy   show
🗑
show Tiny negative particle that flows around a circuit.  
🗑
show Thin piece of wire inside a light bulb that glows when electricity is flowing through it.  
🗑
fuse   show
🗑
show Electrical signal carried by a nerve cell.  
🗑
show A material that does not let electricity flow through it.  
🗑
live wire   show
🗑
show Alternating current at 230 V provided to houses, shops etc.  
🗑
model   show
🗑
nerve   show
🗑
neutral wire   show
🗑
parallel circuit   show
🗑
power pack   show
🗑
show A way of saying how difficult it is for electricity to flow through something.  
🗑
resistor   show
🗑
series circuit   show
🗑
switch   show
🗑
show A resistor that can be adjusted to change the amount of resistance it has.  
🗑
voltage   show
🗑
voltmeter   show
🗑
show complete pathway that electricity flows through  
🗑
show incomplete path that does NOT let electricity flow through  
🗑
conductor   show
🗑
insulator   show
🗑
series circuit   show
🗑
parallel circuit   show
🗑
show something that can stop electricity from flowing and allow electricity to flow; opens or closes a circuit  
🗑
show prevents a fire when too much electricity flows through a closed circuit by breaking and opening the circuit; purpose is to prevent a fire  
🗑


   

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
 
To hide a column, click on the column name.
 
To hide the entire table, click on the "Hide All" button.
 
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
 
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
