Answer: 0.0328 A

Explanation:

Given

No of turns N=920

Length of solenoid L=0.380\ m

Magnetic field B=10^{-4}\ T

the magnetic field at the center of the solenoid is

\Rightarrow B=\mu nI=\mu \dfrac{N}{L}I

Putting values we get

\Rightarrow 10^{-4}=4\pi \times 10^{-7}\times \dfrac{920}{0.380}\times I\\\\\Rightarrow I=\dfrac{0.380\times 1000}{920\times 4\pi}=0.0328\ A

what happens to the current in a circuit if the resitance of the components in the circuit is increased​
Anit [1.1K]

Answer:

The current decreases.

Explanation:

Current and resistance are inversely proportional. The equation connecting current, resistance and voltage is V = IR, where V is voltage, I is current and R is resistance.

Rearranging this equation, you get:

I = \frac{V}{R}

and

R = \frac{V}{I}

If the value of voltage in both equations remains constant, and the value of R decreases, the value of I will increase. Conversely, if in the second equation R = \frac{V}{I} , the value of V remains constant the value of I decreases, then the value of R, resistance will increase.

Thus, it can be seen that the current will decrease as resistance increases and vice versa.

An inclined plane is 5.00 m long and 3.00 m high. What is the ideal mechanical advantage of this machine?
Dvinal [7]
 <span>inclined plane formula is length/hight 

so 5/2= 2.5 

and work= f x d so  
work= 5 x 104 x 10= 5200 W
