Electricity Flashcards
What is a conductor?
A material which allows current to flow through it
What is an insulator?
A material which prevents the flow of current
What do you measure current in and with?
It’s measured in Amps and it’s measured with an Ammeter
What is voltage measured in and with?
It’s measured in volts and measured with an volt meter
What do you measure in parallel?
Voltage
What do you measure in series?
Current
What happens if one bulb (out of two) is unscrewed in a parallel circuit?
The other bulb stays lit up
What happens if one bulb (out of two) is unscrewed in a series circuit?
The other bulb will go out
Why would the bulb stay lit in a parallel circuit when the other one is unscrewed?
Because there is more than one pathway for the current to flow
Why would the bulb to out in a series circuit when the other one is unscrewed?
Because it would make the circuit incomplete
There was a fault in a hairdryer but instead of it being fixed the fuse was replaced. That one blew as well. Why did the fuse blow?
The fuss must have blown because there was too much current flowing to the hairdryer
Then the fault in the hairdryer was repaired but was in place of the 13A fuse there was a 3A fuse. The hairdryer didn’t work. Why?
It wouldn’t work as there would be too much current flowing through
