consider the following circuit. after leaving the switch at the position a for a long time, move the switch from a to b. there will be current oscillations.
- What is the maximum current?
- Consider the following statements
A1. The current flow is counterclockwise
A2. The current is zero
A3. The current flow is clockwise
B1. The charge on the left plate of C is positive
B2. The charge on the left plate of C is zero
B3. The charge on the left plate of C is negative
Which pair of choices below best describesthe situation at t =5/8T, where T is the periodof oscillations in LC circuit? Let the timewhen the switch is moved from a to b be att = 0.


Sagot :

After leaving the provided switch at the given position for a longer time, then its moves given switch from a to b. At t = 0, the left part of the plate C has charge q = max and therefore, the current flowing through it is zero.

Oscillation is the repetitive or periodic variation, usually in time, of a few degree approximately a crucial value or extra one-of-a-kind states. Familiar examples for all oscillation encompass a swinging type of pendulum with alternating current. A wave is stated to oscillate, which means to transport to and fro in a regular, repeating way.

This fluctuation may be among extremes for all position, like force or quantity. Different sorts of waves have one-of-a-kind sorts of oscillations.

Longitudinal types of waves: here oscillation is parallel route of the wave.

The maximum charge stored in the capacitor is,

Q = CE ------(1)

i = 0

At t = t/4, the left part of the plate C has charge q = 0 and therefore, the current flowing through it is clockwise.

i = clockwise

At t = t/2, the left part of the plate C has charge q = -9max and therefore, the current flowing through it is zero.

i = 0

At t = 3t/4, the left part of the plate C has charge q = 0 and therefore, the current flowing through it is counter clockwise

i = counter clockwise

At t = 0, the left part of the plate C has charge q = max and therefore, the current flowing through it is zero.
