The master bedroom and a huge single bed and beside that is also a beautiful and crafted nightstand. next to the Master bed room is the bathroom with an amazing shower that has high pressure and a seat heating/cooling toilet this is the perfect bathroom for anyone that wants the perfect home. going downstairs we have a living room and a very comfortable and expensive and hand crafted couch accompanied by a 100 inch tv. conveniently the kitchen is right next to the living room incase you are ever hungry for a snack. in our modern kitchen we have an fridge, stove, dishwasher, dining table, and a chair. all the appliances are top dollar and very good quality.

A) Unscrew one bulb. If all bulbs go out, they are connected in series. This happens because a series circuit is broken if any bulb is removed, stopping the current flow to all bulbs.

B)  To determine if the three light bulbs are connected in parallel, unscrew one bulb and observe the remaining two. If the remaining bulbs stay lit with the same intensity, they are connected in parallel. In a parallel circuit, each bulb receives the same voltage, and removing one bulb does not affect the others.

C) Bulb A will be the brightest, with four times the intensity of Bulbs B and C. Bulbs B and C will have the same intensity, each being one-fourth as bright as Bulb A.

D) If one of the parallel bulbs is unscrewed, Bulb A and the remaining bulb will have the same intensity. Both will be equally bright.
