Ohm’s Law II
Abstract:
The purpose of this experiment is to demonstrate how non-ohmic devices respond on a direct circuit. Furthermore, we also explored their behavior when they were connected in different configurations. In order to accomplished this we used a capacitor, diode, resistor, and...

metal A
Georg Ohm established experimentally that the current I in a metal wire is proportional to the voltage drop V applied to its ends. ItV When he plotted his results on a graph of V versus I, he obtained a straight line. The equation of the line is known as Ohm’s Law and can be...
Title: Ohm’s Law
Objective: To verify Ohm’s law and determine the equivalent resistance of the resistors arranged in series and parallel.
Theory: Ohm's law states that for an ohmic conductor, the current I through the conductor is directly proportional to the voltage V applied across the conductor...

Formal LabReport Guidelines
In general, the goal of a labreport is to document your findings and communicate their
significance. A good labreport does more than present data; it demonstrates the writer's
comprehension of the concepts behind the data. Merely recording the expected and observed

Q1: explain about the charge, current, voltage and resistance in case of electricity.
Charge In the case of electricity is a property of a particle that experiences force in an electrical field when it is charged. A charge on a object can be that of a negative or positive one, thereby attracting...
