Physics Coursework Investigating Ohms law Introduction Georg Ohm was born in Erlangden and educated at the university there. He became a professor of mathematics in 1817 in the polytechnic school of Nuremberg in 1833, and in 1852 became a professor of experimental physics in the university of Munich, where he later died. In 1826, Georg Ohm discovered the current flowing through a metal wire was proportional to the potential difference across it (providing the temperature remained constant). Proportional means that if you double the potential difference the current will also double. Ohms law: Where: 'V' is the voltage in volts (V), 'I' is the current in amps (A), 'R' is the resistance in Ohms (?). Aim In my coursework I will be looking at the following three components: * A light bulb * A thermistor * A metal wire My aim is to carry out experiments on these three components and find which component out of the three obeys...
