A battery with an emf of 9 V has an internal resistance of 5Ω. Find the terminal voltage of the battery when connected to a resistor of 10Ω. 3. A load of 10Ωwas connected to a battery with an emf of 12 V. Identify the terminal voltage of the battery if its internal resistance...
Mutual inductance is the same if coil L₂ carries the current, which induces a current in coil L₁. Note that electromotive force (emf) can be induced only by changing current and the faster it changes the more emf can be produced. That is, the induced emf is directly proportional...
