from left to right. positive side pushes and negative side pulls.
It means a substance that does not conduct electricity (does not allow electricity to flow through it).
resistance
When there is a closed circuit, there is electricity flow.
no...current is a flow of electricity
flow of electricity is measured by an instrument galvanometer
series circuit
It flows from higher potential to lower potential. simply opposite to direction of electrons flow...
It prevents the flow of electricity since they do not have mobile electrons or mobile ions to allow the flow of electricity.
No. A diode can not be used as a transistor. A diode allows electricity to flow in one direction like a one way street. A transistor works the same way as putting a stop light in the one way street. It lets electricity flow at certain times and keeps electricity from flowing at certain times. Of course a diode only works when electricity is there to flow just like a one way street only works when there are cars there to ride through it.
Electricity dose not truly "flow", it is the exchange of electrons.
It is hard for electric charges to get through.
Yes, electricity can flow through metal.
