In the circuit shown, the pressure coils of two wattmeters are connected to

• A. Neutral Wire
• B. B
• C. R
• D. Y

Answer: (B)

In Two wattmeter method the current coils of the wattmeter are connected with any two lines, say R and Y and the potential coil of each wattmeter is joined across the same line, the third line i.e. B as shown below in the figure . In the circuit B is the common point for both the wattmeter.
