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

When a circuit is arranged in parallel
attashe74 [19]

Answer:

A. There are multiple paths that electrons can take through the circuit, and it is possible for the electron to pass through one circuit component but not another.

Explanation:

Parallel arrangement of components in an electric circuit puts different parts of the circuit on different branches. In a parallel connection, there are multiple paths for the electrons to take, and it is possible for electrons to pass through on circuit component without going through another. This is the reason why If there is a break in one branch of the circuit, electrons can still flow in other branches, and the same reason why one bulb going off in your home does prevent the other components in your home from coming on (your home is wired in a parallel electric circuit).
