Ammeter:
An electromechanical instrument which is used to calculate the amount of current flowing by an electric circuit is known as an ammeter.
It is modified form of a galvanometer. In order to change galvanometer into an ammeter, a low resistance wire is connected parallel to galvanometer. This low resistance wire is known as shunt that is in presence of shunt, a galvanometer act as an ammeter. Ammeter is always linked in series in a circuit.
Intensities of an ordinary light and laser light The intensity (I) of a wave is the energy per unit time flowing through a unit normal area. The light from an ordinary light so

A holiday light string of ten bulbs is equipped with shunts that short out the bulbs when the voltage drop increases to line voltage, which happens when a bulb burns out. Every bul
Write down the electromagnetic wave equation in free space, in terms of vector and scalar potential.
I think it is same as the apex angle of the prism or the angle of the prism. since it decides the angle of deviation as i+e=D+A(angle of the prism),D=deviation.
