Write a 7 page essay on EMF and Internal Resistance.

This paper describes electric current as the manner in which the electric charge flow in a circuit in order to transfer energy portions to regions of resistance like resistors, buzzers, or bulbs) in the circuit. The circuit gets the energy at the start of the circuit where dry cells are producing electrical energy from chemical energy. The batteries available in today’s markets are mostly constructed from materials that possess negligibly small internal resistance. Real batteries do not only provide voltage to the circuit but they also offer some internal resistance. Any device that produces the voltage purely is called an electromotive force (E.M.F.) Which battery is the total energy that is changed electrical energy during the passage of a unit charge through the production point? It forms a voltage and reflects the total amount of energy supplied through the circuit. The terminal voltage a battery produces at a point without the flow of current is the EMF. The units for measuring EMF is volts. All batteries/cells lose energy as heat when they are dissipating current because of the presence of their internal resistance. The voltmeter is used in the circuit to get the emf values. The addition of a resistor in the circuit drops the reading on the voltmeter voltage, v. Meanwhile, voltage does not experience full transfer in the circuit but a portion of it is wasted due to the presence of internal resistance within the battery. The dry cell only possesses internal resistance which converts the energy present into heat. The dry cells EMF together with its internal resistance can alternatively be calculated by other methods. A plot of terminal voltage versus current can help achieve the above. V varies inversely with changes in I to produce a straight line graph. The line equation of y=mx+c, is applicable to the formula of electromotive force, E= Ir.
