Install a switch or timer Examples: Put your refrigerator on a timer so that it does not come on when people are likely to be nearby Use a power strip with a built-in switch to completely turn off a TV or stereo when not in use. Flip off circuit breakers to the bedrooms at night ...
It is used to mantain the vibration at constant frequency in AC circuit.Answer and Explanation: Yes, the peak value of EMF across an inductor can be higher than the EMF across a circuit in an LCR circuit. This occurs at resonance frequency where.....
The ionosphere serves the same function as the stationary rails and connecting resistor in Figure 1, without which there would not be a complete circuit.) Drag on the current in the cable due to the magnetic force F = IℓB sin θ does the work that reduces the shuttle’s kinetic and ...

For example, in the case of a simple electrical circuit consisting of a generator, conducting wires, and resistors, the EMF measures the energy that the generator (source of the electromotive force) provides to the unit load to move from one position to another. In this sense, the ...

This causes electrons to move so that there is an excess of electrons at one point and a deficiency of electrons at a second point. This difference in charge is stored as electrical potential energy known as emf. It is the emf that causes a current to flow through a circuit. ...
