What happens to the current supplied by the battery when you add an identical bulb in parallel to the original bulb?
Marysya12 [62]

Answer:

b. The current stays the same.

Explanation:

In the case given current is supplied by the battery to a bulb . Here, we should know that bulb also apply resistance to the flow of current .

Now, when an identical bulb is connected in parallel to the original bulb .

Therefore, both the resistance( bulb) are in parallel.

We know, when two resistance are in parallel , current through them is same and voltage is divided between them.

Therefore, in this case current stays same in the original bulb.

Hence, this is the required solution.

A standard 12 V car battery has an ampere-hour rating of 40 Ah, whereas a heavy-duty battery has a rating of 60 Ah. How would yo
stiv31 [10]

Answer:

Explanation:

Ah is a unit of charge .

A battery with 12 V and charge capacity of 40 Ah will have energy content

= volt x charge

volt = 12 V

Charge = 40 Ah

= 40 x 60 x 60 A.s

= 144000 coulomb

energy  content = 12 x 144000

= 1728000 J

energy content of heavy duty battery

= 12 x 60 x 60 x 60

= 2592000 J

Ratio = 1728000 / 2592000

= 2 / 3

Current can not be compared as current depends upon the resistance of appliance used . As resistance of appliance is unknown , current can not be compared.
