Electrical Circuits Question #2
Welcome to our mechanical aptitude highlight series. Every week, we post a new free question to help you pass your mechanical aptitude test. We cover levers, maps, pulleys, electrical circuits, gears and tools.I hope you find it useful!
Today we will be covering electrical circuits.
You are given the problem below. The question is as follows:
If the switch S2 is closed and switch S1 remains open, what lights will turn on?
The correct answer is #3, none. The reason why no light is on is because S1 prevents any current from flowing in the circuit. Therefore, there is no light that will turn on.
