Batteries always provide Direct Current (DC).

If you're powering your project with batteries and you need some Alternating Current (AC) in parts of the circuit, then you have to provide an extra section of the circuit to take the DC from the battery and make AC with it.

Some metals have a molecular structure that makes them good conductors. Explain how understanding this relationship can help eng
erastova [34]

Answer:

Explained below.

Explanation:

Conductors can be defined as materials that permit electricity to flow through them easily.

Now, metals have a molecular structure that makes them good conductors because electrons in the atoms of these conductors tend to move freely from one atom to the other. So a majority of metals make good conductors because these metals tend to hold their electrons loosely. In short, it can help engineers make powerful batteries because then it means that they are capable of giving much more electrical energy since nowadays, advanced batteries make use of ion charges for the batteries.

People have proposed driving motors with the earth's magnetic field. This is possible in principle, but the small field means th
fiasKO [112]

Answer:

636.619772368 A

Explanation:

\tau = Torque = 1\times 10^{-3}\ N/m

B = Magnetic field of Earth = 5\times 10^{-5}\ T

A = Area

d = Diameter = 20 cm

Current is given by

I=\dfrac{\tau}{BA}\\\Rightarrow I=\dfrac{1\times 10^{-3}}{5\times 10^{-5}\times \dfrac{\pi}{4}\times 0.2^2}\\\Rightarrow I=636.619772368\ A

The current is 636.619772368 A

max2010maxim [7]

Answer:

c. 5cm \times 8cm

Explanation:

The dimensions 5cm\times 8cm have the highest cross-sectional area combination of 40cm^2.

-Resistance reduces with an increase in cross sectional area.

-Reason-Electrons have alarger area to flow through.
