What is the difference between an electrical circuit and an electronic circuit?
An electrical circuit consists of resistors, capacitors, and inductors, while an electronic circuit includes diodes and transistors.
What is the purpose of a load in an electrical circuit?
To allow electrons to enter at the source and leave at the return or earth ground
TRUE OR FALSE: Series circuits have components connected in multiple paths.
FALSE
What is the symbol for ohm?
Ω
What is an electrical circuit?
A closed path that allows electrons to flow from a voltage or current source.
What are the three basic elements for a circuit to be functional?
A conducting wire, a source of power and an appliances.
Give one example of an intermediate energy: another kind of energy that transforms into electricity and then electricity transforms into another different kind of energy.
Hydro-electric dams that transform the energy of moving water into electricity.
The unit of current?
The amp; the symbol for amp is “A”.
What is the force that moves the electrons along the circuit, passing the resistance in the appliances.
Tension or Voltage
What is a series circuit?
A type of circuit that electrons flow along only one wire.
What is a parallel circuit?
A type of circuit that some current flows along one path and some current along the other path.
What is the amount of electrons that flow along the circuit?
Current or current intensity or current density.
What materials are very good conductors?
Copper and aluminium
What is the best conductor but very expensive?
Silver
What are the types of bulbs?
Incandescent light bulbs, fluorescent lamps and LED’s (light-emitting diodes)
