As a new electrical technician, you are designing a large solenoid to produce a uniform 0.150-T magnetic field near the center o

Kamila [148]

Answer:

I = 21.94 A

Explanation:

Given that

B= 0.15 T

Number of turns N= 3100

Length L = 57 cm

Diameter ,d= 7 cm

We know that magnetic field in the solenoid given as

$B=\dfrac{\mu_0IN}{L}$

$I=\dfrac{BL}{\mu_0N}$

Now by putting the values

$I=\dfrac{0.15\times 0.57}{4\pi \times 10^{-7}\times 3100}$

I = 21.94 A

Therefore current need to produce 0.15 T magnetic filed is 21.94 A.

If an engine can produce 670 J of energy in 1 min, how many watts can it output?

daser333 [38]

Answer:

11.2Watts

Explanation:

Given parameters:

Energy produced by the engine = 670J

Time taken = 1min = 60s

Unknown:

Number of watts it can output = ?

Solution:

This problem entails finding the power of the engine.

Power is the rate at which work is being done.

So;

Power = $\frac{Work done }{time}$

Power = $\frac{670}{60}$ = 11.2Watts
