What is the electromotive force?Components of an Electric CircuitAn electric circuit is the combination of electrical components to form a path for the electrons to flow. A simple circuit consists of a source that is connected to a resistor or a bulb. The flow of the electron in the circuit...
Force is everywhere and it comes in a variety of sizes, directions, and type. We can define Force as the push or pull of an object. Learn Force definition, unit & types of Force with solved examples.
Explain what is electric potential and its basic properties. What is the current (rms) drawn from the 170V line? Explain, with the aid of a diagram, why lines of force must be at right angles to equipotential lines? What is the definition of electric current?

Also, electricity is both a form of energy and a type of matter. Both. Electricity is a kind of low-frequency radio wave which is made of protons. It's a mysterious force which cannot be seen, and yet it looks like blue-white fire that arcs across the clouds. It moves forward at ...
The field lines are like stretched rubber bands; hence they will push the conductor in a downward direction, i.e., the force is downward, as shown in figure (b). This example says that the current-carrying conductor in a magnetic field experiences a force. The following equation determines...
