Sample Text:
The formula is shown below. I = V R Where (I) is the current through the conductor in units of amperes, V is the voltage measured across the conductor in units of volts, and R is the resistance of the conductor in units of ohms. Aim: To investigate the relationship between the electrical potential across a circuit (V), the resulting current (I) and the total resistance (R) of that current. Hypothesis: • As the voltage of a circuit increases the resistance also increases to provide the same current. • As the resistance of a circuit increases the current flowing through the wire will decrease. • As the voltage of a circuit is increased the current of the circuit will increase at the same rate Variables: Part A Independent Variable: Dependant Variable: Controlled Variables: Potential Difference Resistance Current, Power Pack, Mul...

Ohms Law Practical Report

This student studied:
SACE - Year 11 - Physics

Throughout this report, the aim is to investigate the relationship between current, potential difference and resistance with a fixed resistor and a light globe circuit. The investigation will be divided in three parts: Firstly to see if a change in voltage affects the resistance of an Ohmic resistor, Secondly replacing a resistor with a light bulb which is defined as “Non-Ohmic”. Finally, testing the effect of different lengths and thicknesses have on the resistance of the conductor. Ohms law, V = IR will be used to calculate the results which will then lead to a discussion in this report.

Ohm's Law Practical Report

This student studied:
SACE - Year 11 - Physics

The aim of this experiment was to investigate and determine the relationship between voltage, current and resistance, and to prove this using Ohm’s Law. The relationship will be determined by measuring the current, whilst the voltage remains constant and the resistance is varied. The second way to determine the relationships, is by measuring current, keeping the resistance constant and varying the voltage. The third method will be to measure the voltage, whilst keeping the current constant and changing the resistance. In addition, by conducting this experiment, the desired outcome was to prove, validate and verify Ohm’s Law by proving a directly proportional relationship between voltage and current, a proportional relationship between voltage and resistance and an inversely proportional relationship between resistance and current.
