1 of 3

Power source, in this case a 9V battery.

At first, electricity will go through R2 (resistor) then the capacitor (C1).

Capacitor! It will store electrical charges, which will then be used by the relay (underneath on the diagram).

Relay. When there is sufficient electrical charges in the capacitor, it will be released to the relay. The relay then pull the lever so another part of the circuit is close.

When the relay pulls the lever (green circuit), this LED lightbulb and R1 (resistor) will only be turned on.

Power source, in this case a 9V battery.

Electricity is not going through R2 & the capacitor at the moment.

Capacitor! It will store electrical charges, which will then be used by the relay (underneath on the diagram).

Relay. Lever is pulled so different part of the circuit is now on. The lever will come back down momentarily afterward.

Relay pulls the lever, this LED lightbulb and R1 (resistor) are now on!
