Hi
What kind of GPS devices are there that transmit it position and allow other devices, eg: smartphone/computer to locate their position? Are they cheap? I have no knowledge on this, sorry if the question doesn't make any sense.
This is what I'm trying to do:
- Person A have GPS device that...
How do you simulate a sound using multisim?
Im currently trying to simulate a siren circuit from hobbykit but there was no luck.. can some one help?
Or is there any other software that can simulate a sound from a circuit?
Ib=V1/R1 = 0.1mA
Ic=V1/R2 = 10mA
β=100
Am i right?
In designing circuit, do we calculate Ic using β or using the V=IR because in book which im currently studying, all the calculation are using β to calculate Ic but if β is 50 and then the Ic is different right?
Im just so confuse with...
how the charge carriers flow in capacitor
when the switch move to position C, how the voltage in capacitor flow? from A to C? or from B to ground? can someone explain. Tq very much.
Hi guys.
Correct me if i'm wrong.
Calculation for DC is different from AC right?
Resistor, capacitor, transistor calculation for DC is different from AC right?
All component above react differently in DC and AC except resistor. Am i right?
Tq guys.
transistor volrage drop
em.. that's the problem.. Beta by default is 100. The current passing through Ib and Ic is determine by R that we place in. Is that right?
So the problem is, when i try to make switch NPN circuit using Multisim, i dont know what transistor to choose.. :(
there are a...
Re: about capacitor
Im not answering your question.
From my understanding.
Since the resistor is place after the capacitor, so the capacitor will charge instantly to its max in 0s and the current is the same since it's a series circuit. Calculate the I using ohm law.
Is that right? If not...
transistor voltage loss
where do i get the datasheet for all transistor?
and voltage drop.. what its for? all the calculation for vd is used for what? tq quys
transistor voltage drop
what voltage drop for?
how to know which transistor to use when design circuit?
eg. 2n3404. 2n its npn,and the number?
i follow a book and design a simple circuit using multisim.. and when i want to select the transistor, i get confiused.. i dont which transistor to use..
How to identify a PNP or NPN transistor in real component? A guy from the electronic shop said it can't be tell?
And anyone have multisim free software?
Tq a lot!
em tq guys for spending ur time to guide me. I want to learn about creating a frequency circuit.. like alarm or remote control car.. so what book is best for me? i dont know how current flow in big circuit.. and i already know how to calculate transistor, resistor and etc. I have certificate on...
