"A 60 watt bulb is connected to 120V plug. What is the current in the lighted bulb?

a. 0.25 A
b. 0.5 A
c. 2 A
d. 4 A
"

 

Answer:

B. 0.5 A

Explanation:

The current in the lighted bulb is 0.5 A.

If we are looking for the current, based from the original formula, heres what we should be using as a formula:

Current (amperes) = Power (watts) ÷ Voltage (volts)

Current = 60 Watts ÷ 120 volts the answer would be 0.5 Amperes.

As a result, if were going to base this in the original formula, this is what yore going to do:

Power (watts) = Voltage (volts) x Current (amperes)

60 Watts = 120 Volts x 0.5 Amperes

CODE: 9.22.4.4.

If an actor engages in a relationship with her husband, in another relationship with her family and in a third relationship with her village, does that make her a member of three cultures?   Answer: Yes, because culture affects our personal habits and preferences. Explanation: But before anything else, let us first define what culture is. Put in mind that culture is as complex as the universe, with many different definitions, and explanations. Most of us would think that culture is about food, clothing, language, and/or celebration that are shared by a specific group, however these are only some of its elements.

It includes groups that we are born into, such as gender, race, national origin, class, religion, etc.  Like most things that make us who we are, the development of our cultu

"Budoy, a junior high school student, lifts a 3 kg book from the floor into a cabinet 2.0 m high. With reference to the floor, how much potential energy does the book acquire? a. 5.88 J b. 58.88 J c. 588.88 J d. 5888.88 J "   Answer: The 3 kg books that Budoy lifts 2.0 m above the ground will have a potential energy of b. 58.88 J Review: Before enything else, we need to clarify the concpet of potential energy. Explaining it will make things more easier and easily understood. Potential energy is the energy that an object possess within it, which is defined by its mass, distance from a relative mass or point of reference, and gravitational force. Know that we know its definition, we know understand that your potential energy may differ on the point of reference you are using. Example, if you are on the rooftop of a 7-storey apartment, your potential energy will vary from each floor. Your potential energy from the rooftop in reference to the 5th floor will be di
