Long before humans understood electricity, we can only rely on natural sources of light
such as the moon or candles to brighten our nights. But in 1879, that changed due to
Thomas Edison’s invention of the light bulb. We are told to use Multisim to create a
circuit that may be used in the lighting of a bulb. I will be using the equation V=I*R to
calculate the values of each aspect of the circuit. In the design, I am asking how I can
calculate the voltage if I were to use the formula V=I*R. In the discussion I will be
asking, why did the value of the voltage in my first attempt fail to add up to the 15V? The
voltage of the battery was given to the circuit from the get go, but I did not have a
multimeter set up at each individual resistor. In conclusion, after using a multimeter on
each individual resistor I put into the circuit, I created a working circuit using a 15V
battery.
Introduction
Long before humans understood electricity, we can only rely on natural sources of
light such as the moon or candles to brighten our nights. But in 1879, that changed due to
Thomas Edison’s invention of the light bulb. We are told to use Multisim to create a
circuit that may be used in the lighting of a bulb. We were told to use the different
components from the simulation to power it from the lab (see fig.1). Then we are told to
create our own circuit consisting of three resistors of any value, and also to use a battery
of 15V.
Background Theory
In this section of the lab report, I will be stating the equation to be used in the future
to be V=I*R.
Design
In the design, I am asking how I can calculate the voltage if I were to use the formula
V=I*R. If the set voltage is 15V then I must use the values of the resistors to figure out
the voltage, this means I must add all the values of the resistors and multiply it by the
total percent and it must equate to 15V.
Procedure
-Use 1kohm resistor and select a 5% tolerance. (see fig.1)
-Create a 200ohm resistor, SPST switch, DC_Power, Ground and multimeter.(see
fig.1)
-Using 15V battery, create a circuit using 3 resistors of any value and have it run
successfully. (see fig. 3)
