Objective:
This experiment is focused on slowing the rate of arrangement passing arrange
circuits. First, a circuit is an electrical device that allows charged particles, in this case
electrons, to pass through conductors to produce electricity such as light in a light bulb.
Within this experiment, we will compare the measured resistance (equivalent resistance)
of a manufactured resistor and compare it to printed/expected resistance, in addition to
the combining them into different arrangements such as series and parallel.
Theory:
During this experiment, we will be testing Ohm’s Law by measuring and
comparing the resistance of arrangement in different arrangement and voltages to by
increasing the voltage, and measuring the resistance. However, to compare the measured
resistance to the calculated resistance we first must use the equation
V=RI
(1)
where the
V
represents the potential drop across a conductor, measured in Volts (V); and
R
represents the resistance of the conductor, measured in Ohms (Ω) and lastly the
I
represents the current in the conductor that is measure in amperes, more commonly
known as Amps (A). When rearranged we can derived the equation for a resistor in a
circuit.
Keeping mind that we are also measuring resistors in different arrangements,
there are also two different equations to measures parallel and series arrangements.
In the parallel circuit arrangement the equation for equivalent resistance is:
