 Like we know, a circuit won’t work without a conductor or electrical components.  Therefore we need a conductor like copper wire to connect the electrical components.

 Circuit can be connected in series or parallel.  We can’t connect a house’s lights in serie because if one bulb stop working the rest of the bulbs won’t work.

 At serie circuits the electrical components will be connected in one ongoing lane.

 At parallel the circuit splits into more lanes.

 Use of components that let current flow or not.  Cell- A power source used to let current flow.  Switch- Lets current flow or stop the current flow.  (LDR)-Light depended resistor- Uses light to let the current flow.  Thermistor- Uses temperature to stop current or to let it flow.

 The product of the process.  bulb – A component that brings forth light, because of the resistance.  Motor- It drives other objects with a rotational movement.

 Bulb  Cell + -  Switch  Power source  Battery + -

 Variable resistor  Diode  Resistor  Fuse

 Voltmeter  Ammeter

 This is when there is an ongoing flow of electrons without any resistance in a circuit.  It is very dangerous because the electrons flow the whole time and the battery heats up.  Therefore we must add resistance or a switch to the circuit.  Safety is the most important priority at electricity.

 To process information in electrical compliances we can use LOGIC gates.  Logic gates work with binary code to process.  ‘Bi’ – means “TWO”  Therefore we use the numbers “0” and “1”

 Logic gates work like a switch and we can use switches to learn how it works.  At an AND-gate the one and the other one must be ‘1’ for the bulb to work.  At an OR-gate the one or the other one must be ‘1’ for the bulb to work.
