Draw a neat sketch and explain the use of CT and PT for measurement of power in a single-phase circuit?

Question 1

Question 2

If wattmeter of proper range is not available or if voltage and current ranges are high we can usr CT and PT of suitable ratio. Connect the CT and PT as shown in figure. The reading of wattmeter can be multiplied by the ratio to get the actual power.
