o-na [289]

In the context of the loop and junction rules for electrical circuits, a junction is where three or more wires are joined.

Answer: Option 2

<u>Explanation: </u>

An electrical circuits consists of many points like branch, loop, junction, series, bridge, etc. So, loops are the ones where the output of one circuit will act as feedback of the same circuit. If two or more wires passes through a single point, then that point is termed as junction.

If two or three junction connect each other they are termed as branch. Like these several other parameters are there with different rules in the circuit system. For electrical circuits, junction and loop rules state that a junction is the point where more wires joined together.

What does a light bulb marked 100 W mean? (A) Uses 100 A of energy per second. (B) Uses 100 J of current per second. (C) 100 C o
Mandarinka [93]

Answer:

(E) none of these.

Explanation:

first that all we need the meaning of a Watt

<em>" is a unit of power. In the International System of Units (SI) it is defined as a derived unit of 1 </em><em>joule</em><em> per </em><em>second</em><em>,[1] and is used to quantify the rate of </em><em>energy</em><em> transfer."  </em>

<em>definition taken from wikipedia.org</em>

now with this concept we have that:

100 W means 100 J/s .Therefore it uses 100 J energy per second

therefore on the answers don't mention this three terms together

Joules, energy and second so the answer must be.

(E) None of these

Use the claim to answer the question.
Pachacha [2.7K]

Scientific evidence such as reflection and photoelectric effect has proven the wave-particle model of electromagnetic radiation to be true.

<h3>What is electromagnet radiation?</h3>

Electromagnetic radiation is radiation produced as a result of the interactions of the electric and magnetic fields.

Some forms of electromagnetic radiation include:

  • radio waves
  • microwaves
  • ultraviolet radiation
  • visible light

Electromagnetic radiation can be described using a wave model or a particle model.

The wave property of electromagnetic radiation include:

  • diffraction
  • reflection
  • refraction

The particle property of electromagnetic radiation include:

  • photoelectric effect
  • Compton effect.

Therefore, the wave-particle model of electromagnetic radiation is correct because it can be backed up by experiments and evidence.

Why is an energy source needed in order to have a working circuit
PolarNik [594]
Well, everything needs a source of energy to work. Without some source of energy, a circuit cannot work. For example, when you're tired, you can't function well as opposed if you a had good rest,  a healthy breakfast, coffee, etc.
