172. 1kW Resistor Tolerance – Silver Band
Build the circuit shown on the left and turn on the switch (62). Press
the press switch (61) and you will see the heart LED (69) and colorful
LED (72) light. Release the press switch (61) and the heart LED (69)
and colorful LED (72) will stay bright briey and then turn dim. If the
1kW resistor in this circuit had a 4th band that was silver, then the
actual resistance of the resistor could be anywhere from 0.95*1,000
= 950W to 1.05*1,000 = 1050W.
173. 5.1kW Resistor Tolerance – Silver Band
Replace the 1kW resistor (42) in project #172 with the 5.1kW resistor
(43) and turn on the switch (62). Press the press switch (61) and
you will see the heart LED (69) and colorful LED (72) light. Release
the press switch (61) and the heart LED (69) and colorful LED (72)
will stay bright for a little while and then turn dim. If we had a 5.1kW
resistor with a 4th band that is silver, then this would mean that the
actual resistance of the resistor could be anywhere from 0.95*5,100
= 4,845W to 1.05*5,100 = 5,355W.
174. 10kW Resistor Tolerance – Silver Band
Replace the 1kW resistor (42) in project #172 with the 10kW resistor
(44) and then turn on the switch (62). Press the press switch (61) and
you will see the heart LED (69) and colorful LED (72) light. Release the
press switch (61) and the heart LED (69) and colorful LED (72) will stay
bright for a while and then turn dim. If we had a 10kW resistor with a
4th band that is silver, then this would mean that the actual resistance
of the resistor could be anywhere from 0.95*10,000 = 9,500W to
1.05*10,000 = 10,500W.
175. 100kW Resistor Tolerance – Silver Band
Replace the 1kW resistor (42) in project #172 with the 100kW resistor
(45) and then turn on the switch (62). Press the press switch (61)
and you will see the heart LED (69) and colorful LED (72) light. Release
the press switch (61) and the heart LED (69) 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 red, then this would mean that the actual
resistance of the resistor could be anywhere from 0.95*100,000 =
95,000W to 1.05*100,000 = 105,000W.
