On Exam or assignment you might be asked to give Two examples of situations or applications where electrical circuits are used. This is a very important question regarding electrical engineering or related field. Below are the answers that you might want to verify with your teacher or lecturer.
A “situation” is a set of circumstances.
When I have a dark “situation” (that’s when there’s not enough light), I can operate a switch in an electrical circuit and bulb is lit. The light from the bulb chases the dark away.
When I have a cold “situation” I can operate another switch which allows current to flow through an electric heater. The hotness causes a warm “situation”.
