The following three resistors (Ohms) are in parallel with one voltage source. What is the total current running through circuit?

Zepler [3.9K]

Explanation:

The total resistance Rt is given by

1/Rt = 1/Ra + 1/Rb + 1/Rc = 1/5 + 1/4 + 1/7 = 0.593

or Rt = 1.69 ohms

The total current I running through the circuit is

I = V/Rt = 2.37 A

The secondary coil of a step-up transformer provides the voltage that operates an electrostatic air filter. The turns ratio of t

Sphinxa [80]

Answer:

The power consumed by the air filter is 9.936 watts

Explanation:

It is given that, the secondary coil of a step-up transformer provides the voltage that operates an electrostatic air filter.

Turn ratio of the transformer, $\dfrac{N_s}{N_p}=\dfrac{46}{1}$

Voltage of primary coil, $V_p=120\ V$

Current in the secondary coil, $I_s=1.8\times 10^{-3}\ A$

The power consumed by the air filter is :

$P_s=I_s\times V_s$ ...........(1)

For a transformer, $\dfrac{N_s}{N_p}=\dfrac{V_s}{V_p}$

So, $P_s=I_s\times (\dfrac{N_s}{N_p})\times V_p$

$P_s=1.8\times 10^{-3}\times (\dfrac{46}{1})\times 120$

$P_s=9.936\ Watts$

So, the power consumed by the air filter is 9.936 watts. Hence, this is the required solution.

Monochromatic light falls on a slit that is 2.30×10−3mm wide. Part A If the angle between the first dark fringes on either side

slava [35]

Answer:

Wavelength, $\lambda=1.28\times 10^{-6}\ m$

Explanation:

Given that,

Width of the slit, $d=2.3\times 10^{-3}\ mm=2.3\times 10^{-6}\ m$

The angle between the first dark fringes on either side of the central maximum is 34 degrees

To find,

The wavelength of the light used.

Solution,

The equation of maxima is given by :

$dsin\theta=n\lambda$

n = 1 here

$\lambda=\dfrac{d\ sin\theta}{n}$

$\lambda={d\ sin\theta}$

$\lambda={2.3\times 10^{-6}\times sin(34)}$

$\lambda=1.28\times 10^{-6}\ m$

So, the wavelength of the light used is $1.28\times 10^{-6}\ m$ . Hence, this is the required solution.

If a document is to be produced using a duplicating

blsea [12.9K]

Answer: A. at the point which

is twice the focal lenght of the lens of the camera

Explanation:

When a certain document is to be produced through the use of a duplicating camera, it should be noted that the camera should be placed at the point which is twice the focal lenght of the lens of the camera so as to get the exact copy of the document.

It should be noted that placing the camera between the principal and a point twice the focal lens of the camera lens or beyond a point that's twice the focal length will not produce the document.

Therefore, the correct option is A
