What does a simple circuit require?

d

Explanation:

A complete Electrical Circuit is required in order to make electricity practical. Electrons must flow from and return to the power source.

There are three different circuit types, all require the same basic components:

1. Power Source is needed to supply the flow of electrons (electricity).

2. Protection Device prevents damage to the circuit in the event of a short.  

3. Load Device converts the electricity into work.

4. Control Device allows the user control to turn the circuit on or off

5. Conductors provide an electrical path to and from the power source.

Explanation:

okay i have so many questions. but the big one here is: um wt..f is this mess? ?

answer: the exterior temperature of commercial jet planes as they leave the stratosphere and return to the ground increases steadily.

explanation:

the lower most layer of atmosphere is troposphere which extends from 0 to 12 km above the surface of the earth. the temperature initially decreases as distance is increased from the earth's surface. commercial jets fly in lower part of the stratosphere. the stratosphere extends upto 50 km. the temperature in stratosphere starts rising again due to presence of ozone which traps the uv rays.

thus, when the planes leave the stratosphere and return to the ground, the exterior temperature increases steadily.
