Current = 300 A, Resistance = 40 ohms, and Voltage =?

Ohm’s law states that V=IR V=(300)(40) V=12000 V.
Therefore, choice A is the right one.

A concentric magnetic field perpendicular to the direction of the current in a wire is created by a constant current flowing through it. The right-hand grip rule can be used to determine the field’s direction.

There are only three possible modulations. three types of modulation: phase, frequency, and amplitude.

Photons are released, so A and B are wrong. Since atom population inversion is accomplished, option D is erroneous. Since a laser does, in fact, emit monochromatic, coherent light, option C is accurate.

The quantity of magnetic field lines that flow through a specific region is known as magnetic flux. ‘B’ stands for the magnetic flux density, ‘A’ for the area, and ‘theta’ for the angle between the two vectors. The formula to compute magnetic flux is BA cos(theta).

Magnetic flux would be ‘BA’, the maximum value, when theta is zero, indicating that the two quantities are parallel to one another.

The International System of Units (SI) uses a farad (F) as the standard unit of capacitance (C). It shows how well a material can retain an electric charge. The most common units of measurement for electrical capacitors are farads, microfarads (µF), or nanofarads (nF).

The capacitance of a capacitor in which one coulomb of charge results in a potential difference of one volt is equivalent to the SI unit of electrical capacitance.

Farad = Coulomb / volt

The charge of the down quark is −1/3.

It is proposed that there are six quarks: (1) Up (2) Down (3) Strange (4) Charm (5) Bottom, and (6) Top.
