Answer:
The power consumption by the CD player is 0.87 watts.
Explanation:
Given that,
Voltage of the portable CD player, V = 3 volt
Maximum current drawing the CD player, [tex]I=290\ mA=290\times 10^{-3}\ A[/tex]
We need to find the maximum power consumption by the CD player. We know that the electrical power of any appliance is given by :
[tex]P=V\times I\\\\P=3\ V\times 290\times 10^{-3}\ A\\\\P=0.87\ W[/tex]
So, the power consumption by the CD player is 0.87 watts. Hence, this is the required solution.
