Op-amp comparator compares the input signal only with zero-voltage level.define
true and false with reason?

For generating high frequency signals RC oscillators are preferred over LC oscillators.true and false with reason?

Would it be possible to set up a home or a room in a way the person living within would be remotely controlled electronically, without the use of biohacking per se? In other words, could one be controlled via electromagnetism where hardware equipment could be remotely controlled as to reorient the subject's movements slightly, and can regular PC hardware such as HDMI and USB+Micro chipset devices (unifying receivers, lan controllers...) be used remotely for the purpose of applying force to the point of influencing a human biologically speaking?

E.g. I plugged a chromecast into an hdmi port on my PC fo an hour and it is now the biggest magnet I have seen ever, anything metal sticks to it, and this has happened with various devices and i am exponentially feeling loss of control over my body movements, my arm will twitch or hit a cable repeatedly, oddities I am trying to explain without assuming an unlikely biohacking scenario (typical one).

Thanks!

Determine between 60 watt bulb and a 100 watt bulb which one is more powerful give reason

Determine between 60 watt bulb and 100 watt bulb, which is more powerful and give your reasons

if the total charge stored is 240 micro Coulomb. Then calculate,
A, calculate the net potential difference
B, calculate the charge to be stored on C3
Given
C1=24 micro Coulomb
C2=4 micro Coulomb
C3=8 micro Coulomb

A circuit when connected to an AC source of 12 V gives a current of 0.2 A. The same circuit when connected to a DC source of 12 V, gives a current of 0.4 A. The circuit is
(1) Series LCR
(2) Series LR
(3) Series RC
(4) Series LC

to design a biasing current that is independent of power supply and temperature.

You will need to do both the circuit design and layout design of your project.

Design Targets:
The value of the output biasing current should be 25x10^-5 A.
You should ensure that the total current requirements of your circuit is as low as possible.

Operating Conditions
VCC: Min 2.7V, Typ 3.0V, Max 3.3V
Temperature: Min -45°C, Typ 25°C, Max 125°C

4 conductors meet at a node:


Given that I1 = -6 A I2 = 8 A and I3 = 7 A, use Kirchoff's current law to calculate the current I4. Give your answer in Amps.
