The shadow cast by the sodium flame when illuminated by the sodium lamp should become lighter.
<h3>What is Zero current point ?</h3>
The interruption phenomenon in high power circuit breakers is referred to as current zero (CZ). Today, it is unlikely that high voltage circuits could be inexpensively disrupted using anything other than an electric arc.
electric field -
The electric force per unit charge is referred to as the electric field. It is assumed that the field's direction corresponds to the force it would apply on a positive test charge. From a positive point charge, the electric field radiates outward, and from a negative point charge, it radiates in.
In order to provide the lamp with a virtually constant current rather than a constant voltage in order to ensure reliable operation, the lamp is often supplied by an AC voltage source connected in series with an inductive ballast. To minimise resistive losses, the ballast is often inductive rather than just resistive. Because the sodium flame's shadow is growing lighter and this lamp's current is going toward its zero-current point.
