A 120-V electrical line in a home is connected to a 100-W lightbulb, a 180-W television set, a 230-W desktop computer, a 1050-W toaster, and a 240-W refrigerator. How much current is flowing in the line

Explanation:

It is known that relation between voltage and power is as follows.

                Power (P) = Voltage (V) × Current (I)

or,               I =

Since, it is given that the elements are in parallel so the currents will get added. Therefore, total current in the line will be as follows.

       I =

         =

         =

         = 15 A

Therefore, we can conclude that 15 ampere current is flowing in the line.

convex lenses are thicker at the middle. rays of light that pass through the lens are brought closer together (they converge). a convex lens is a converging lens. when parallel rays of light pass through a convex lens the refracted rays converge at one point called the principal focus.
