Short Test



In the last hour, you experimented with various switches. When you built the
light for the refrigerator, the elevator, the blinking light, the tower with the
blinking warning light, the stop light control, the alarm system or the
handdryer, this was always concerned with the turning on or the turning off of
lights or a motor with various switches such as a push button, a magnetic
switch or a light barrier.

Therefore, for the next experiments you should always be sure as to how
circuits work and how you read or draw a circuit diagram. Remember that
when working with higher voltages and currents, electrical power can even
be life endangering! So, make a habit of being very careful even when using
our models from the building set.

To test your present knowledge, carefully Which switches must be closed so that the
examine the following circuit diagram. following lights are illuminated? Write the
numbers in column 2.



The light to be Closed switches
illuminated is:
Only light 1
Only light 2
Only light 3
Only light 4
Lights 1 and 2
Lights 2 and 3
All lights
Which switches may not be closed at the same time because otherwise there
will be a short circuit?
