176. 1kW Resistor Tolerance – Gold Band
Build the circuit shown on the left and turn on the switch (62). Press
the press switch (61) and you will see the star LED (70) and colorful
LED (72) light. Release the press switch (61) and the star LED (70) and
colorful LED (72) will stay bright for a little while and then turn dim. If the
1kW resistor (42) in this circuit had a 4th band that was gold, then the
actual resistance of the resistor could be anywhere from 0.9*1,000 =
900W to 1.1*1,000 = 1100W.
177. 5.1kW Resistor Tolerance – Gold Band
Replace the 1kW resistor (42) in project #176 with the 5.1kW resistor
(43) and turn on the switch (62). Press the press switch (61) and you
will see the star LED (70) and colorful LED (72) light. Release the press
switch (61) and the star LED (70) and colorful LED (72) will stay bright
for a while and then turn dim. If we had a 5.1kW resistor with a 4th
band that is gold, then this would mean that the actual resistance of the
resistor could be anywhere from 0.9*5,100 = 4,590W to 1.1*5,100
= 5,610W.
178. 10kW Resistor Tolerance – Gold Band
Replace the 1kW resistor (42) in project #176 with the 10kW resistor
(44) and then turn on the switch (62). Press the press switch (61)
and you will see the star LED (70) and colorful LED (72) light. Release
the press switch (61) and the star LED (70) and colorful LED (72) will
stay bright for several seconds and then turn dim. If we had a 10kW
resistor with a 4th band that is gold, then this would mean that the
actual resistance of the resistor could be anywhere from 0.9*10,000
= 9,000W to 1.1*10,000 = 11,000W.
179. 100kW Resistor Tolerance – Gold Band
Replace the 1kW resistor (42) in project #176 with the 100kW resistor
(45) and then turn on the switch (62). Press the press switch (61)
and you will see the star LED (70) and colorful LED (72) light. Release
the press switch (61) and the star LED (70) and colorful LED (72)
will stay bright for several seconds before turning dim. If we had a
100kW resistor with a 4th band that is gold, then this would mean
that the actual resistance of the resistor could be anywhere from
0.90*100,000 = 90,000W to 1.1*100,000 = 110,000W.
