After a financial crisis in 1910‚ Durant had to step down as president of General Motors‚ but that didn’t keep him from the auto-industry for long. “Durant quickly joined forces with race-car driver Louis Chevrolet to create a new brand to challenge the Ford Model T. Louis Chevrolet’s successes as a race-car driver and determination at the wheel of early racing machines gained

resistance of the cell‚ to identify errors involved and deal with them in the most effective way and maintain a safe working environment at all times. Background EMF (electromotive force) is a measure of work done per unit of charge and is measured in volts. Internal resistance is resistance in ohms of the cell. I will be using a 1.5V battery in the experiment. I will measure the voltage and current using multimeters. Calculation method I intend to rearrange the equation ‘ε=Ir+IR’ to form ‘V= -Ir +ε’

This emf is proportional to the rate of change of flux linkages. Putting mathematically‚ e= dψ dt (1) Where‚ e is the induced emf in volt and ψ is the flux linkages in Weber turn. Fig. 1 shows a Figure 1: Flux linkages of a coil coil of N turns. All these N turns link flux lines of φ Weber resulting in the Nφ flux linkages. In such a case‚ ψ = Nφ and e=N dφ dt volt (3) (2) The change in the flux linkage can be brought about in a variety of ways • coil may be static and unmoving but the flux linking

Demonstrate an understanding that potential difference (voltage) is the energy transferred per unit charge passed and hence that the volt is a joule per coulomb 9. Investigate the relationship between potential difference (voltage)‚ current and resistance 10. Explain how changing the resistance in a circuit changes the current and how this can be achieved using a variable resistor 11. 2.8 Use the equation: potential difference (volt‚ V) 5 current (ampere

The Volt Count Alessandro Giuseppe Antonio Anastasio Gerolamo Umberto Volta was the father of the volt. He was born in Italy. He made the first cell in the 1800s. The cell that he made was not really a battery‚ but it was the most advanced attempt of making a battery in his time‚ it produced a steady electrical current‚ but did not work well over time; it was called the Voltaic pile. The voltaic pile was made of two electrodes of zinc and copper and sulphuric acid as the electrolyte. His name
