Complete Question

In 1.0 second, a battery charger moves 0.54 CC of charge from the negative terminal to the positive terminal of a 1.5 VV AA battery.

Part A How much work does the charger do?

Part B: What is the power output of the charger in watts?

Answer:

Part A  

 [tex]W =   0.75 \  J  [/tex]

Part B

 [tex]P =  0.75 \  W [/tex]

Explanation:

From the question we are told that

   The time taken is  t = 1 s

   The amount of charge is  Q =  0.54 C

    The voltage of the battery is  [tex]V  =  1.5 \  V[/tex]

     

Generally the workdone is mathematically represented as

    [tex]W =  Q *  V[/tex]

 =>     [tex]W =   0.54 *   1.5 [/tex]

 =>     [tex]W =   0.75 \  J  [/tex]

Generally the power output is mathematically represented as

      [tex]P =  \frac{W}{t}[/tex]

=>   [tex]P =  \frac{0.75}{1}[/tex]

=>   [tex]P =  0.75 \  W [/tex]
