Why current of potential coil should be lagging by 90 degrees? and why we are taking lagging condition for energy meter?
please use the pointer on the screen
sir can you pls explain how torque Td1 and Td2 is produced by the interaction of fluxes and opposite eddy currents?

sir how to find the directions of Td1 and Td2?
sir aap thoda slow bataya kigiye, bhut fast bata rhe the wattmeter. aur sir power factor find krne ke liye bhi bata digiyega ,NTPC ke exam me power factor find krne ke liye pucha tha ,jo hm nhi bana paye

Next time I'll try to explain slowly..... I've already discussed the concept of power factor calculation by two wattmeter method.... I'll discuss its application when I'll discuss previous year GATE problems.
