The power of a certain CD player operating at 120 V rms is 20.0 W. Assuming that the CD player behaves like a pure resistor, find (a) the maximum instantaneous power; (b) the rms current; (c) the resistance of this player. 31.20 .. In an L-R-C series

a.  

b.  

c.  Ω

Explanation:

Data

power average:

operating voltage:

a.The maximum instantaneous power: average power is one-half the maximum power.

so the maximum instantaneous power is:

b. To find current:

  The formula to find rms current is:

c. To find the resistance of the player:

   Ω

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
