13. a step up transformer has 250 turns on its primary and 500 turns on it secondary. when the primary is connected to a 200 v and the secondary is connected to a floodlight that draws 5a, what is the power output? show all of your work.

The output power is 2 kW

Explanation:

It is given that,

Number of turns in primary coil,

Number of turns in secondary coil,

Voltage of primary coil,

Current drawn from secondary coil,

We need to find the power output. It is equal to the product of voltage and current. Firstly, we will find the voltage of secondary coil as :

So, the power output is :

or

So, the output power is 2 kW. Hence, this is the required solution.

it is the second option.
