Q

A parallel palte capacitor of capacitance $20 \mu F$ is being charged by a voltage source whose potential is changing at the rate of 3 V/s . The conduction  current through the connecting wires , and the dispalcement  current through the plates of the capacitor , would be  resectively :

• Option 1)

zero, $60 \mu A$

• Option 2)

$60 \mu A , 60 \mu A$

• Option 3)

$60 \mu A , zero$

• Option 4)

zero , zero

Option 1)zero, Option 2)Option 3)Option 4)zero , zero

Out of the following options which one can be used to produce a propagating electromagnetic wave?

• Option 1)

A charge moving at constant velocity

• Option 2)

A stationary charge

• Option 3)

A chargeless particle

• Option 4)

An accelerating charge

Total radiant Flux (Power) -   q = Charge  = Acceleration of particle c = Speed of light in vacuum - wherein The accelerated charge particle produce EM wave. P is total radiant flux emitted by charge at any instant.    Electromagnetic wave can be produced by an accelerating charge. Option 1) A charge moving at constant velocity This option is incorrect. Option 2) A stationary charge This...
