Why in partial fractions does the power of the denominator have to be one more than that of the numerator, when splitting up the expression. Skip to 5:30. Thanks.
while most appliances require DC, things like light bulbs can operate on AC, which menas the lights switch on and off. This is where i live at 50hz which is like it going on and off ever 10 milliseconds, so we don't really notice. I'm not sure about any other appliance, usually the more...
Most kitchen appliances require a DC(direct current) for them to work as this is a constant current, while AC fluctuates between different directions it travels in the circuit which can stuff up appliances. AC current is used as it is easy to transport over long distances and there is less power...
thanks guys I understand now, the middle of the amplifier characteristics graph is called the quiescent point which adjusts the input AC voltage so it's in the linear region.
okay let me mkae it clearer... this is in regards to a question in a practice vce physics unit 3 exam.
There is a transfer characteristics graph of a transistor amplifier. the linear region of the input voltage is between 1mV and 7mV's. while the output is between 1V and 9V's.
The question...
If we have a input voltage that has a voltage higher then the linear region of the amplifier characteristics graph, what does amplifier biasing exactly do to the wave so there is no clipping, distortion or cut-offs and saturations.
