Question
Why do most flashlights have batteries connected in series? Why are the individual cells in a car battery connected in series? What are the essential features in the construction of a flashlight? Make a sketch of the circuit. What does the term "complete circuit" mean? Wires for a speaker in another part of the house do not work. How could you check to see if the wires are broken someplace in the walls? What happens when a light bulb bums out? What happens to the complete circuit when you unscrew a bulb from its socket? Are your household appliances wired in series or parallel? Explain. Assume that you have an old-fashioned string of Christmas tree lights that are wired in series. How would you discover which is the one that is burnt out? Why do you blow a fuse (or pop a circuit breaker) if you plug too many appliance in at one time? What is the purpose of a fuse in household circuits? Which would last longer, a battery connected to two bulbs wired in series or two bulbs wired in parallel? Why? Why might it be preferable to use two 60-watt bulbs in a hallway rather than a single 120-watt bulb? What happens to the total resistance of the circuit as you add more and more bulbs in parallel? What happens to the current? Are the headlights in your car connected in series or parallel? How do you know?Explanation / Answer
(1) , (2) Batteries are connected in series to give greater voltage with the same capacity( Amp-hour)
(4) A complete circuit is a closed circuit.
(6) The filament gets too hot and burns out. The break in the filament stops the current flow.
(7) The circuit becomes incomplete if the initial circuit is series, if it is parallel then the circuit remains complete.
(8) Household appliances are connected in parallel. because if one of the appliances is broken then the remaining ones function without any problems in a parallel circuit.
(9) The burnt out buld will have a break in the filament.
(10)(11) When there are too many appliances connected at one time the total current drawn at that time would be greater than the fuse can handle. Hence the fuse gets too hot and melts and burns out. This is done in order not to damage any other appliances because of the high current.
