Give an example of static electricity | Lightning |
A positive charge has... | More protons than elecrons |
A negative charge has... | More electrons than protons |
How do objects become electrically charged? | When atoms gain or loose electrons |
What is an insulator? | A material through which charge cannot flow |
What is a conductor? | A material through which charge can flow |
What is a lightning rod? | A sharp metal rod that is placed above if tallest part of the building, if lightning hits the metal rod the electrons travel to earth along the copper conductor and the building is undamaged |
What is current electricity? | Electricity that comes through sockets and plug s. It has to be in a circuit. An example of this is a switch |
What is voltage? | Potential differnece |
What is voltage measured in? | Volts(V) |
What is the difference between current and voltage? | Current is a measure of the number of charges flowing along the wire, voltage is the measure of the ability of the charges to do a particular task |
What is the resistance? | The opposition to the flow of electrons |
What is resistance measured in? | Ohm |
What is the hint used to measure voltage(V), current(I) and resistance(R)? | Voltage over current times resistance |
