Objectives:
The objective of this experiment was to verify that the magnitude of the electric force
between two point charges is inversely proportional to the square of the distance between the
charges, but is directly proportional to the product of the t
Objective
Our object is to confirm Ohms law by analyzing the dependence of the electrical current
as a function of voltage and as a function of resistance. Also, we studied the current flow and
voltage in series and parallel. Finally, the lab determined t

This experiment in the laboratory was done to study the relationship between electrical
energy and heat energy to verify the principle of conservation of energy for the electrical energy
being converted to thermal energy. To determine the conver

We have completed this laboratory activity to become familiar with the Wheatstone
bridge method of measuring resistance, to determine resistivity of metal conductors and to study
the phenomenon that the resistance of wire varies directly with it
Objective
To study a source of the electromotive force (emf) by using the potentiometer method and
to distinguish between the emf and terminal voltage of the source of the emf.
Theory
When a current I exists in the battery, there is a potential drop, equa

Friction is the force that resists the relative motion of one surface in contact
with another. There are two types of friction: static and kinetic. Usually, the kinetic
frictional force is less than the maximum value of the static frictional forc
