Answer:
Output voltage is 1.92 volts.
Explanation:
Given that,
Number of turns in primary coil,
Number of turns in secondary coil,
Input voltage,
We need to find the voltage output of a transformer used for rechargeable flashlight batteries. For a transformer, the number of turns and the voltage ratio is given by :
So, the output voltage is 1.92 volts.
Answer:
Intensity of the next bright fringe will remain same.
Explanation:
The question is based on Young's double slit experiment, since its about bright fringe, the interference here is constructive.
Young's condition for constructive interference is given by:
dsin
where,
d = slits distance from eachother or width of the slits
= wavelength
n = interferance order
Also, we know that in Young's experiment, the fringe intensity is given by:
where,
= phase difference
Therefore, in absence of phase difference i.e., , the intensity of the next bright fringe will not change and it will remain same.
