Answer:
The current in a resistor decreases by a factor of 4.
Explanation:
I = 
Where (I) is the current, (E) is the voltage and (R) is the resistance.
Decreasing the voltage by 4 gives;
I = 0.25
Since you have multiplied
by 0.25,
You have to multiply I by 0.25 so the current decreases by a factor of 4.

Explanation:
The laws of reflection hold true for all the reflecting surfaces either spherical or plane. Therefore, the plane mirror, concave mirror and the convex mirror all will follow the laws of reflection.
