If we instead connect this headlight and starter in series with the 12.0 V battery, how much total power in W would the headlight and starter consume? (You may neglect any other resistance in the circuit and any change in resistance in the two devices.)

If and be the power consumed by the headlight and starter respectively, then the total power consumed will be

Explanation:

We know that electric power () is given by

where '' is the applied voltage and '' is the resistance.

If we consider that '' and '' be the power consumed by the headlight and starter respectively, then the resistance () of the headlight and the resistance () of the starter can be written as

If the headlight and the starter in connected in series, then equivalent resistance () will be

So the total power () consumed will be given by

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!
