For the circuit given above, the Thevenin's resistance across the terminals $$A$$ and $$B$$ is

For the circuit given above, the Thevenin's voltage across the terminals $$A$$ and $$B$$ is

An average-reading digital multimeter reads $$10V$$ when fed with a triangular wave, symmetric about the time axis. For the same input an rms reading meter will read.

The figure shows a three phase delta connected load supplied from a $$400V,$$ $$50Hz,$$ $$3\phi $$ balanced source. The pressure coil and current coil of a wattmeter are connected to the load as shown. With the coil polarities suitably selected to ensure a positive deflection. The wattmeter reading will be.
