Quiz on 555 Timer Monostable Mode

What is the primary function of a 555 timer in monostable mode?

• Generating continuous oscillations

• Producing a single output pulse

• Voltage regulation

• Signal amplification

In monostable mode, the output of a 555 timer is typically:

• A continuous high state

• A continuous low state

• A single pulse triggered by an external signal

• An alternating square wave

Which of the following is the output pulse width formula for a 555 timer in monostable mode?

When a 555 timer is in monostable mode, the output pulse duration depends on:

• The supply voltage

• The values of R and C

• The external load

• The input trigger pulse width

In monostable mode, how many times does the 555 timer output pulse occur after each trigger?

• Multiple times

• Once

• Twice

• Constantly oscillates

What is the state of the output immediately after the trigger pulse is applied to a 555 timer in monostable mode?

• High

• Low

• Oscillating

• No change

In monostable mode, what happens to the output after the timeout period?

• It remains high

• It returns to low

• It begins oscillating

• It produces another pulse

Which component controls the timing interval for the output pulse in a monostable 555 timer circuit?

• External load

• Internal oscillator

• Timing resistor and capacitor

• Feedback resistor

Which of these is a common application of the 555 timer in monostable mode?

• Frequency modulation

• Voltage amplification

• Delay circuits and pulse generation

• Power supply regulation

In monostable mode, once the capacitor reaches a threshold voltage, the output:

• Remains high

• Drops to low

• Alternates between high and low

• Oscillates continuously
