What is critical resistance in circuit theory?
With respect to an RLC circuit, the critical resistance is the resistance which would critically dampen the circuit. This means a resistance lower than the critical resistance would create an under-damped situation, and higher than the critical resistance would create an over-damped situation. An underdamped circuit will ocillate, an overdamped circuit will decay exponentially over a long period of time. The critically damped circuit will immediately decay to zero (time dependent on the values of the circuit elements)
What are the applications of a monostable multivibrator?
applications of monostable multivibratorA monostable is a circuit that will respond to a stimuli only once and only for a period. Its usage can be many depends of applications
Why a capacitor of higher value is preferable?
It can hold a very large amount of charge and release the same over along period of time. It depends in what circuit you are using it. For power supply decoupling and regulation, bigger is better. If you change the capactior value in a timing or tuned circuit, it will not behave as designed.
What is an arc voltage in a circuit breaker?
ARC VOLTAGE is the voltage that appears across the contacts of circuit breaker during the arcing period, during which the current flow is maintained in the form of an arc. The arc voltage value is low except for the point at which the current reaches zero when the arc voltage rises rapidly to a peak value.
