During 57 seconds of use, 330 C of charge flow through a microwave oven. Compute the size of the electric current.
swat32

Answer:

5.78amps

Explanation:

Given data

Time t= 57 seconds

Charge Q= 330C

Current I= ??

The expression for the electric current is given as

Q= It

Substituting we have

330= I*57

I= 330/57

I=5.78 amps

Hence the current is 5.78amps

What is the maximum value of the electric field in an electromagnetic wave whose average intensity is 7.35 w/m2 ?
anastassius [24]

The maximum value of the electric field in an electromagnetic wave is 23.54 V/m.

<h3>What is an electromagnetic wave?</h3>

The oscillations between an electric field and a magnetic field produce waves known as electromagnetic waves, or EM waves. In other words, magnetic and electric fields oscillate to form electromagnetic (EM) waves.

Electromagnetic waves are produced when an electric field and a magnetic field interact. They are referred to as "electromagnetic" waves as a result. An electromagnetic wave's electric field and magnetic field are perpendicular to one another (at right angles). Additionally, they are perpendicular to the EM wave's direction.

In vacuum, EM waves move at a fixed speed of 3.00 x 108 ms-1. Neither the magnetic field nor the electric field can deflect them. However, they might show diffraction or interference. An electromagnetic wave can pass through any medium, including vacuum, solid materials, and air. It can spread or move from one area to another without the use of a medium. On the other hand, mechanical waves (such as sound waves or water waves) require a medium to propagate. Transverse waves include EM waves. The height and distance between the highest and lowest points of two successive waves, respectively, are thus used to measure them.

The highest point of a wave is referred to as the "crest," and the lowest point as the "trough." A variety of frequencies can be created by dividing up electromagnetic waves. The electromagnetic spectrum is what is meant by this. Radio waves, microwaves, infrared waves, X-rays, gamma rays, and other types of waves are EM waves.

Two loops of wire are arranged so that a changing current in one will induce a current in the other. If the current in the first
patriot [66]

Answer:

The current in the second loop will stay constant

Explanation:

Since the induced emf in the second coil, ε due to the changing current i₁ in the first wire loop ε = -Mdi₁/dt where M = mutual inductance of the coils and di₁/dt = rate of change of current in the first coil = + 1 A/s (positive since it is clockwise)

Now ε = i₂R where i₂ = current in second wire loop and R = resistance of second wire loop.

So,  i₂R = -Mdi₁/dt

i₂ = -Mdi₁/dt/R

Since di₁/dt = + 1 A/s,

i₂ = -Mdi₁/dt/R

i₂ = -M × + 1 A/s/R

i₂ = -M/R

Since M and R are constant, this implies that i₂ = constant

<u>So, the current in the second wire loop will stay constant.</u>
