Electricity Flashcards
Give a word for :
Property of component that restricts flow of charge
Resistance
What are the requirements of a circuit to work ?
- source of energy
- closed circuit
- conductor
Give a word for :
Component that offers the resistance
Resistor
Explain the uses of heat on electricity
An electrical current transfers energy to the particle in a bulb filament, producing light that the light filaments emits
Explain the effects of electricity on magnet fields
A current causes a magnetic field ( such as in electromagnets )
Give examples of electrolysis
Oxygen to hydrogen gas
Copper to chlorine gas
What is a series circuit
Provides only one pathway for the current passing through it
What is a parallel circuit
Two or more pathways for current passing through it
What are the benefits of a series circuit
- Greater current that causes the bulb to burn more brightly
- more cells increase
What are the benefits of parallel circuits
- bulb will glow with same brightness as series circuit
- two or more cells with allow bulb to burn for longer
