The gain increases.
It gets brighter.
current decreases and resistance increases
As current increases, the electromagnet strength will increase.
That will depend on the temperature coefficient of resistance of the device, which could be positive (i.e. resistance increases with increasing temperature), negative (i.e. resistance decreases with increasing temperature), or zero (i.e. resistance is unaffected by temperature changes).
The PF will increase
When the bandwidth of an amplifier increases, it means the amplifier can process a wider range of frequencies. This can result in better signal quality and improved overall performance of the amplifier. However, increasing bandwidth may also lead to increased noise and distortion in the output signal.
when a change happens, positive feedback is a response to that change that encourages the change further, instead of trying to inhibit the change like negative feedback.
It simply means that when one variable increases, the other increases as well.
It increases.
It increases.
You get a positive number which is larger than the original.
what happens if we remove Rc in RC coupled amplifier
During positive feedback loop, e.g. a gland activates a hormone and the hormone in turn activates the gland. After the hormone knows that it is being activated by the gland, the hormone signals the gland to produce more of the hormone. This is positive feedback loop.
Usually yes, but you do have to take migration, immigration into account.
Dehydration is not an example of positive feedback. Positive feedback loops amplify or reinforce a pathway or process, while dehydration is a state where the body lacks adequate water, leading to negative effects on various bodily functions.
The output waveform will be limited to the difference between the supply and ground (or between the positive and negative supplies). This causes distortion of the output waveform.
wht happens if WBC increases?
