I = Q/t
By changing values
I = 4000/12

We obtain 333.3 amps.

Option C is correct since photons’ momentum is determined by de Broglie’s equation P=h/lambda, and “lambda” can be calculated by dividing “f” (frequency) by “f” (speed of light).

The following formula can be used to determine a photon’s momentum:

p = h/λ

where λ is the photon’s wavelength, p is its momentum, and h is Planck’s constant.

The connection between wavelength and frequency can also be utilized:

c = λf

where f is the photon’s frequency and c is the speed of light.

When the equation above is rearranged, we obtain:

λ = c/f

When we replace momentum in the expression with this value of λ, we obtain:

p = h/(c/λ)

p = h/(c/(c/f))

p = hf/c

Thus, a photon’s momentum can be written as hf/c.

The symbol for angular velocity is ω.

As stated,

ω = 60 rev/min

1 rev = 2π rad, and 1 min = 60 s. Adding values,

ω = 60 x 2π/60 rad/s

= 2π rad/s

Option D is therefore the right choice.

The ripple frequency in full wave rectification is twice that of the input frequency.

On the other hand, it is equivalent to the AC supply frequency for a half wave rectifier.

For rectification of the full wave = 2× f

= 2 × 50 Hz = 100 Hz

When the alternating current is positive, which occurs during 180° of the A.C. cycle, a half-wave rectifier conducts and blocks current during the remaining 180°.

As you can see, a full-wave rectifier conducts current for twice as long during both of the 180° phases of an AC cycle.

Because it uses both half-cycles of the input, a full-wave rectifier is twice as efficient as a half-wave rectifier.

A “time base generator” is the circuit that supplies voltage to X-plates. This kind of electronic circuit is utilized in electronic displays like television sets and oscilloscopes. In a CRO (Cathode Ray Oscilloscope), the electron beam’s horizontal deflection is controlled by a sawtooth waveform produced by the time base generator. This makes it possible to display signals that change over time, like waveforms and pictures.
