The voltmeter is connected across the two ends of a conductor to measure the potential difference across the two terminals of the conductor. The voltmeter is connected across the two poles of a battery...
The inductive reactance is different from the ohmic resistance where the inductive reactance for a coil of zero resistance does not cause loss in electric energy, because the current resistance is due to the...
Some electric circuits consist of many branches and are too complicated to be managed by Ohm’s law because the electric current passing through them is different in each branch, For such cases, a German...
The emf of an electric cell (battery – source) is the total work done inside and outside the cell to transfer electric charges in the electric circuit, If we denote the emf of the...
