Avoltage v is applied to the primary coil of a step-up transformer with a 3: 1 ratio of turns between its primary and secondary coils. a resistor r connected to the secondary dissipates a power p = 100 w. how much power is dissipated by the same resistor when the ratio of turns in the transformer is changed to 24: 1 and the same input voltage is used?

Explanation:

Let are the number of turns in primary and secondary coil of the transformer such that,

A resistor R connected to the secondary dissipates a power

For a transformer,

...............(1)

The power dissipated through the secondary coil is :

.............(2)

Let are the new number of turns in primary and secondary coil of the transformer such that,

New voltage is :

...............(3)

So, new power dissipated is

So, the new power dissipated by the same resistor is 6400 watts. Hence, this is the required solution.

here are some information of the future of geothermal energy:

-the future of geothermal energy can pretty much be summed up with a single word: more

-scientists plan in going deeper than 120 meters

-we are hoping that one day, we will get all of our energy from renewable energy sources such as geothermal energy

hope this !

first thing first of the answer is with technology. second thing second thing is that the big bang theory did not happened u see they say it did but what they dont realize is that like dinasures are still a round they might deny it but they and look at these 12 foot human skelteons they find lets see didnt the bible say something about giants. hope this peace.
