146. t for 1kW Resistor and 100mF Capacitor
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) light. Release
the press switch (61) and the star LED (70) will stay bright briey and
then turn dim.
The t for this circuit is 1,000*100e
-6
= 0.1 second.
147. t for 5.1kW Resistor and 100mF Capacitor
Replace the 1kW resistor (42) in project #146 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) light. Release the press switch (61) and the
star LED (70) will stay bright for a little while and then turn dim.
The t for this circuit is 5,100*100e
-6
= 0.51 second.
148. t for 10kW Resistor and 100mF Capacitor
Replace the 1kW resistor (42) in project #146 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) light. Release the press switch (61) and
the star LED (70) will stay bright for a while and then turn dim.
The t for this circuit is 10,000*100e
-6
= 1 second.
149. t for 100kW Resistor and 100mF Capacitor
Replace the 1kW resistor (42) in project #146 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) light. Release the press switch (61) and
the star LED (70) will stay bright for many seconds before turning dim.
The t for this circuit is 100,000*100e
-6
= 10 seconds.
