Using the time delay graph determine the approximate capacit

Using the time delay graph, determine the approximate capacitance needed with a 10,000 Ohm resistance to obtain a 10-msec delay with a 555 monostable multivibrator. 0.008 mu F 0.08 mu F 0.8 mu F 8 mu F In troubleshooting a pulse circuit by waveform comparison, you should use a logic probe. a logic scope. an oscilloscope. a pulser. Which one of the following probe circuits will activate the LED when the probe touches a logic 0?

Solution

12) (B) 0.08uf

13) (D) Pulser Circuit

14) circuit in option (A) - because the between +ve and -ve terminal of LED must be +ve.
