Circuit diagram - Simple circuits. What is the Twentieth statement of the video clip?
if we were to draw a circuit diagram for the circuit then here is what it will look like ?
note that there will be two circuit diagrams for this.
this one is when the switches off and the electric current is not flowing through the circuit.
we see that no arrow heads are shown here
this circuit diagram is when the switches on
here the circuit is complete and the current is flowing the arrow heads are used to show the direction of the electric current which is always from the positive to the negative terminal of the battery
What is the symbol for switch? there are two symbols for a switch.
This symbol is used when the switch is on and this symbol is used when the switch is off
Circuit diagram - Simple circuits. What is the Twenty-First statement of the video clip?
if we were to draw a circuit diagram for the circuit then here is what it will look like ?
note that there will be two circuit diagrams for this.
this one is when the switches off and the electric current is not flowing through the circuit.

this circuit diagram is when the switches on
here the circuit is complete and the current is flowing the arrow heads are used to show the direction of the electric current which is always from the positive to the negative terminal of the battery
now here is a question for you. we know that when the electric current flows between the two ends of the filament; the filament heats up
Circuit diagram - Simple circuits. What is the Twenty-Second statement of the video clip?
this heating up of the filament results in its glowing and this is how we receive light from the bulb

Circuit diagram - Simple circuits. What is the Twenty-Third statement of the video clip?
this heating up of the filament results in its glowing and this is how we receive light from the bulb
but if this filament is broken then will the bulb glow?
no it won't. this is because if the filament breaks the circuit will be broken
