1. PMDC motors Dont stop at 2xI(A) at startup, unless forced to do so, by external circuitry.
2. The "break" voltage will far exceed the applied voltage. Since you have not specified the FET type, it is difficult to analyse the problem.
3. Parallel components are 'dangerous':!::!: Unless you...
Sorry guys, but I dont see the "bulb" details anywhere. ie., Voltage or Current rating.
ha-jurgen!
You cannot "When the coil starts then i can convert high voltage to high current, needed to light a bulb"
P=VxI (primary = P=VxI secondary (theoretical)
Practically there is IxIxR losses and the...
Re: RADIO CONTROL
Any RC car remote TX RX can be used for any purpose.
1. The Cheap RC cars have 2 sets of switches Fwd/Rev & Left/Right. On the RX, these are available on 4 pins ie,. 2 pins each.
2. A relay with a series diode, can be connected in place of the Motors to the RX board. Even a...
MCT has an additional MosFET as the input gate. This increases sensitivity and reduces gate current.
The problem: it cannot be turned OFF by reversed polarity as in an ordinary thyristor..
Re: Transistor
The Transistor was described as " Trans-fer of current across a re-Sistor" by its inventor.
No matter what you do , The base bias voltage may remain same or vary slightly but the base current can be varied widely, resultingin a corresponding increase in Collector current.
(The...
The Rectifier Transformer is simply an AC Transformer + Rectifiers to convert AC to DC. This is used to feed DC to the corrodable buried or water immersed structures.
The idea is to make the buried or immersed metallic structure a cathode. This will prevent corrosion of these metals.
The Actual...
Sound Waves:
Audio Frequency AF =20Hz to 20000Hz.

Ultra high frequency UHF 9 300–3000 MHz...
The Clicking sound could be the Speaker protection Relay, that switches on after the Amplifier and other stages have stabilised.
Check the speaker cable for loose/ cut connection. Some times the wire has come off and their will be over load. The Protection " ckt will switch off the System to...
