What else can I help you with?
Is signal ac or dc?
ac
Is a stepper motor easier to maintain than a normal ac motor?
A stepper motor is more easier to maintain than a normal ac motor. Ac motor is a seal motor under pressure. A stepper can easliy be open and the interwheels can be fixed and cleaned.
Why not you use ac instead of dc to electronic components?
AC is easier and cheaper to send from the generators to the consumers than DC is.
Can bjt amplify dc?
A bipolar junction transistor (BJT) can amplify DC signals, but it requires proper biasing to operate in the active region. By applying a DC input signal to the base, the BJT can control a larger DC current flowing from the collector to the emitter, effectively amplifying the input. However, the amplification is limited to small variations around the bias point, and the BJT cannot amplify a constant DC level without an input signal. Therefore, while BJTs can amplify DC, they are primarily used for AC signal amplification.
What will happen when a single diode is connected to a transformer with ac signal?
it convert ac signal into dc signal But it will give only half-wave rectification.
Why is an AC current system used in a domestic electrical supply?
Alternating current (AC) is easier to transmit over long distances than is direct current (DC).
What is the operation of a rectifier?
The operation of a rectifier is to conver a AC signal to a pulsating DC signal
What is an AC source?
signal value changes with time
Is IC 555 can generates an Ac output signal?
no
Can transistor be used to increase the strength of an ac signal?
Yes, a transistor can amplifiy an a.c. signal.
Working of AC tachometer?
A ac tach usually works off the AC signal of the alternator on a bus or truck. The alternator produces AC power that is rectified to make DC current to run the car, truck or bus. There is a TACH terminal or in North American buses more than 10 years old it is called a stator tap. The AC voltage changes speed (frequency) with the engine and the Tachometer reads that as a signal Early or inexpensive ones are actually run on the AC current.
Why you add a positive voltage to the ac signal to allow a transistor to amplify ac signal?
It depends on how you bias the transistor. If you ground the emitter, which is very common, you will need to offset the input signal so you can amplify the full voltage swing.
