Draw a circuit diagram using proper symbols that includes a three-cell battery, a motor and a lightbulb in parallel, a voltmeter to measure the voltage of the motor, an ammeter to measure the current through the light bulb, and a switch to operate the entire circuit.

The modern-day generator works on the principle of electromagnetic induction discovered by michael faraday in 1831-32. faraday discovered that the above flow of electric charges could be induced by moving an electrical conductor, such as a wire that contains electric charges, in a magnetic field.

In atoms, the electron carries a negative elementary or unit charge; the proton carries a positive charge. the two types of charge are equal and opposite. in an atom of matter, an electrical charge occurs whenever the number of protons in the nucleus differs from the number of electrons surrounding that nucleus.
