5 series connection with two LEDs
Here we use a second white LED in the circuit. The light will
be a little brighter. The brightness is enough to read at night.
And once again, there are two brightness levels. Depending
on the situation, you can decide how much light is needed.
Series connection
In series connection, the same current flows through two or
more consumers. It is an “unbranched circuit” because there is
only one way the current can flow. This means that the current
is the same at each point.
