Answer:

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.

How can you prove the mechanical nature of sound by a simple experiment
Kruka [31]

Answer:

That is, mechanical waves cannot travel through a vacuum. This feature of mechanical waves is often demonstrated in a Physics class. A ringing bell is placed in a jar and air inside the jar is evacuated. Once air is removed from the jar, the sound of the ringing bell can no longer be heard.

If you were in charge of designing a wire to carry electricity across your city, state or province, which of
Anon25 [30]

Answer:

Thin, aluminium and buried underground.

Explanation:

When it comes to electrification of a state or province, some characteristics of the wire to use must be considered. This would help to minimize and avoid power loss and wire burns.

i. The wire to use should be thin, and a quite number can be twisted one against the other so as to increase the surface area for heat dissipation.

ii. Aluminium wire is more preferable for this project. It has a high melting point, and reduces energy loss.

iii. Burying the wire underground through an insulator is the best choice, though expensive but would preserve the wire from external influence.

What affect would using a 12V car battery have on the operation of your circuit? (Do not try this.) What would happen to the cur
k0ka [10]

Answer:

Incomplete question

This is the completed question

If the resistor in the circuit had a larger resistance then the current would be then have to be proportionally smaller. Because the batteries each give off 1.5 volts then the current would have to be the variable that would change. What affect would using a 12V car battery have on the operation of your circuit? (Do not try this.) What would happen to the current? What would happen to the resistor?

Explanation:

Using ohms law as our basis

Ohms law state that, the voltage in an ohmic conductor is directly proportional to the current

V∝I

Resistance is the constant of proportionality

Then

V=iR

Since we want a relationship between current and resistance.

then, I=V/R

So, current is inversely proportional to Resistance

as the current increase the resistance reduce and as the current reduces the resistance increases.

a. So, increasing the voltage from 1.5V to 12V increases the current In the circuit because voltage Is directly proportional to I.

From ohms law

V=iR

When v =1.5V

I=1.5/R

When V increase to 12V

I=12/R

I.e, it increases by a factor of 8. Eight times it's initial value

b. Now, the resistance in the circuit is the constant of proportionality and it doesn't change in a given circuit expect when using a variable resistoa r like rheostat.

What is your velocity if it takes you 40 seconds to walk around a circle of 50meters 3 times?​
Shtirlitz [24]

Answer:

0 m/s

Explanation:

Velocity is displacement over time.  Displacement is the distance between your initial position and your final position.  If you walk in a circle, you end up back where you started, so your displacement is 0.  Therefore, your velocity is also 0.
