Question
In the monostable multivibrator, the external resistance is 1K Ohm, and the output pulse width is 10m seconds. Determine the value of the capacitance C (in micro-Farads).
Solution
The monostable multivibrator is a one-shot timer circuit. The output pulse width (T) of a monostable multivibrator can be calculated using the formula:
T = 1.1 * R * C
Where: T is the time period, R is the resistance, and C is the capacitance.
Given that T = 10ms (or 0.01 seconds) and R = 1K Ohm (or 1000 Ohms), we can rearrange the formula to solve for C:
C = T / (1.1 * R)
Substituting the given values:
C = 0.01 / (1.1 * 1000)
C = 0.01 / 1100
C = 0.00000909 Farads
Since 1 Farad = 1,000,000 micro-Farads (uF), we convert C to micro-Farads:
C = 0.00000909 * 1,000,000
C = 9.09 uF
So, the value of the capacitance C is approximately 9.09 micro-Farads.
