The resistors don't look like their values are all that important, really, as long as the parts can take the extra voltage (and any surges or spikes which could occur) it's probably ok, just test it w …

I think your professor is messing with you, if he means in general (as in any DC resistance compared with any other AC resistance), No. However, having said that, if he's referring to a specific compo …

Assuming that the transmitter is just a transmitter, power draw should not be dependent on data. … However, the volume of data in a txt is far less than in a video stream so the txt uses the same power but less energy as the radio is only transmitting for a brief instant. …

Our ideal switching power loss is $$P = E*f\ \ \ or\ \ \ 0.5*C*f*V^2$$ Where P is power and f is frequency. … So higher frequencies need proportionally more power, but higher voltages need exponentially more power and because higher clocks tend to go hand in hand with higher core voltages, the power required can …

If you add lots of bypass capacitors to ensure a smooth clean supply rail, you could use a single big buck-boost DC-DC regulator. Everything on your list will run on 3.3V, as the voltage of a lithium …

Aside from input power and time, you also have the power absorbed by the object being heated (just because it's a 700W microwave, doesn't mean 700W is always delivered, much like a 600hp sports car doesn't … So the material will partially dictate how quickly a fixed power source will heat that object. …

Real power is the instantaneous product of V and I as opposed to the average product of V and I (which is called the apparent power as it is the sum of real and reactive power and represents the, well. … .. apparent power draw of the device). …

Now power is the amount of effort required to do all this, think about how much effort it takes to suck water up a straw... now try with a 50mm drainage pipe, you'll be lucky to move anything at all, it … Volts (pressure) = Amps (flow) * Resistance and Power (effort) = Volts*Amps (or flow * change in pressure, which interestingly still gives you power in watts) …

If the LDO can handle the current AND it has sufficient heatsinking so that it doesn't get too hot (as long as it's less than 75'C your are probably OK as pretty much all electronics are rated to 125' …

Second: 1W of DC power gets you 1W*efficiency worth of RF power irrespective of frequency. … A common example is when you are interested in the "noise power" of an amplifier as this is often expressed in dBc/Hz, but this is a normalized unit that really means power/bandwidth. …

Well, if you're only interested in the high frequency part and can afford some drift and non-linearity, I'd recommend a voltage divider where you have a capacitor as the HV element (basically a high-p …

The terminology is a bit different between AC and DC circuits, I think that's where the confusion stems from (Earth = dirt ground as opposed to electrical ground). AC Neutral is the equivalent of DC …

In these situations it's important that the signal coming out looks that same as the one coming in (albeit at a higher power). …
