How much less power is wasted if the electricity is delivered at 50,000 v rather than 12,000 v?

1 answer:

8 0

We are asked in this problem to determine the power wasted given the two voltages: 50,000 and 12,000 volts. By physics, the formula to determine power using volts is expressed as P = VI where P is in watts, V is in volts and I, current, is in Amperes. In this case, we just have to plug the given data to the equation named.

1) P1 = 50,000*I
2) P2 = 12,000 * I

P1 - P2 = (50,000-12,000)*I
ΔP = 48,000 I
So the power wasted then is equal to 48,000 times the current employed to achieve power. I should be specified as well to determine the exact difference.

Does a emp effect electronics it hits forever and does it fry it

I recently received the following question regarding EMP effects: “What will happen to vehicles with electronic ignitions, a Chevy with an ignition module, but they are not hooked to a battery, with no path for electricity to follow, can it do damage? There may not be power on the grid, but what about a generator? Can a drill that was not plugged in still be able to run?”

The short answer is, maybe.

Which of the following statements are true?

Tems11 [23]

Answer:

1) A time-varying magnetic field will produce an electric field.

4) A time-varying electric field will produce a magnetic field.

Explanation:

1) A time-varying magnetic field will produce an electric field.

TRUE

time varying magnetic field will produce electric field which is given as

$E = \frac{r}{2}\frac{dB}{dt}$

2) Time-varying electric and magnetic fields can propagate through space only if there is no matter in their path.

FALSE

Time varying electric field and magnetic field will induce each other and it can travel through any medium as well as it can travel without any medium also

3) Electric and magnetic fields can be treated independently only if they vary in time.

FALSE

electric field can be due to stationary charge and magnetic field due to current carrying elements so it is not compulsory to have time varying

4) A time-varying electric field will produce a magnetic field.

TRUE

Time varying electric field will produce magnetic field given as

$B = \frac{\mu_o\epsilon_o A}{2r}\frac{dE}{dt}$

he magnetic coils of a tokamak fusion reactor are in the shape of a toroid having an inner radius of 0.700 m and an outer radius

RideAnS [48]

Answer:

B = 4.323 T

Explanation:

We are given;

Inner radius; r_i = 0.7 m

Number of turns; N = 890 turns

Current; I = 17 KA = 17000 A

Formula for the magnetic field inside the toroid along the inner radius is given by;

B = (μ_o × N × I)/(2πr)

μ_o is vacuum of permeability with a constant value of 4π × 10^(-7) H/m

Plugging in the relevant values, we have;

B = (4π × 10^(-7) × 890 × 17000)/(2 × π × 0.7)

B = (2 × 10^(-7) × 890 × 17000)/(0.7)

B = 4.323 T
