how to use bands to measure resistance

first band represents first digit, second band represents second digit, third band represents multiplier (multiply the number by it), fourth band represents the tolerance

how to create Req=200 using only 100 ohm

connect 2 100 ohm resistors in series

how to create Req=150 using only 100 ohm

connect 1 100 ohm resistor in series with 2 100 ohm resistors in parallel

how to create Req=25 using only 100 ohm

connect 4 100 ohm resistors in parallel

why is the actual resistor value different from the theoretical value

the theoretical value is assuming ideal conditions, which is not always possible

how to calculate the minimum resistance value needed to achieve pmax

pmax > vi = v^2/r
plug in pmax and v to solve for r

does your calculated resistance value meet the current restraint of 10 mA

using the r value calculated using pmax and v, r has to be greater than 200, we chose 220
pmax = vi = i^2*r
plug in pmax and the measured value of r to find i
we found that our resistance does not meet the current restraint, which can be fixed by raising the resistance

when is pmax achieved

when Rab=Rth

does our vout values match the theoretical values

we changed our range, so yes it does match, if we didn't change it, our range was too small so our vout would not match
