# Resistor Essay Examples

Resistors are used in various real life applications to perform tasks that involve: limiting the current that goes through a section of a circuit, introducing a voltage drop in a circuit, generating heat and the protection of components of a circuit. It is important to calculate the resistance of resistors so that the electrical circuits…

Title: Investigating the current – potential difference relationship for a metal wire. Aim: To design an experiment that will facilitate an I – V Graph to be ascertained of a metal wire and thus find the resistance of the wire by deriving the inverse of the gradient of the graph. Skill: Planning & Designing Theory:…

The graph is showing a straight line through the origin. This means that as the voltage increases, the current also increases uniformly. A graph of Voltage and Current for a resistor was the same, when I did the experiment. This means that the liquid behaves like a resistor. Which was what we were trying to…

As you can see from these results as the light intensity increases, the resistance decreases. I need to find the range of light levels the LDR can detect and distinguish how sensitive it actually is. The maximum resistance it is possible to get from the LDR is 550k?. This is when there is maximum light…

What happens to the strength of an electric field when the charge on the test charge is halved? 6. What happens to the electric potential energy of a charged particle in an electric field when the particle is released and free to move? 7. A test charge experiences a force on . 30N on it…

Once the electrons are moving this “flow” factor is called the Current and can be measured by the uppercase letter “I” or the symbol “A” (Amps). PotentialDifference Resistance= Current In my investigation we were finding out how resistance is affected by the legnth of a wire. For this we needed potential difference and current. When…
