Your body resistance is high- hard to push electrons through.

Bandwidth control is used to ensure that people do not exceed their given bandwidth amount. If the limit is exceeded, they are charged extra as a penalty.

You should use the scale that shows correctly your supply voltage.

Most Hall-effect switches provide either a logical output or an open-collector output.

If the output is logical, you can expect the value to be between 0 and your supply voltage.

If the output is open-collector, you must bias the output to your supply voltage with a resistor; otherwise you will always read "0". If biased, the output will be between 0 and the voltage bias.

If you are not certain of which type you have, try finding the datasheet on the Internet; otherwise, you can always bias the output to your supply voltage; if you properly choose the resistor, it should not adversely affect the behaviour of the logical-level output.

I would suggest trying 1 kOhm with a 5 V supply; this gives a bias current of 5 mA, which most Hall-effect sensors should be able to cope with.

There are other Hall-effect sensors that provide linear output, but this answer is about a Hall-effect switch.

A half bridge inverter is an electronic circuit that uses different phases to do what it needs to do. A full bridge inverter is a single phase device so a half bridge is more complicated than a full bridge.

Efficiency is typically associated with minimizing losses in a circuit. If you have no load you couldn't compute efficiency. If there is a load you need to determine what you are trying to measure. For example, in an incandescent light bulb a lot of power is wasted in heat. So if light is what you are looking for an incandescent bulb isn't very efficient. A compact fluorescent would be more efficient. However, if you were using a light bulb to power an "Easy Bake" oven it would be more efficient.

DRL cannot invert signals.

You can connect 4 resistors in series-parallel, i.e. two in series, both in parallel with another two, and the effective resistance would be the same as one resistor. Similarly, you can connect nine resistors in 3x3 series-parallel, or 16 resistors in 4x4 series-parallel, etc. to get the same resistance of one resistor.

It depends on from which country the signal is broadcasting .

In general it is the range of kilo to mega Hz.

usually, throughout the world 87.5 MHz to 108.0 MHz is used .

The range of any RF signal is dependant on the power output, the height and efficiency of the aerial. So there is no information to give you an answer.

The difference between FM and AM, is that FM has the 'capture effect'. This is where the strongest signal wins, at the receiver.

AM signals on the same frequency, will compete and beat together, so you will hear both stations at the receiver.

FM signals at the receiver will detect the strongest signal and supress a weaker signal on the same frequency, so you only hear the stronger signal.

If you are tuning into a weak FM signal, the background hiss will increase with range until you cannot hear the signal over the noise.

FM is more desirable for quality signals containing music, at close range.

AM suffers more from other stations but does not get noisey with range, so weak communications can be heard at a greater range. This is desirable for communications.

A current source converter (CSC) is a power electronic device that converts electrical energy from one form to another, specifically by controlling the output current. It operates by using a current source as its input, often employing thyristors or other controlled devices to manage the flow of current. CSCs are commonly used in applications like high-voltage direct current (HVDC) transmission and motor drives, providing advantages such as improved power quality and efficient energy transfer. Their ability to handle bidirectional power flow makes them suitable for renewable energy integration and flexible grid operations.

Cathode rays are electrons.

Adjacent channel interference nearby frequency leak into passband. The problem can be worse if an adjacent channel user is transmitting in very close range to a subscriber receiver. This problem is referred as near far affect. By Kazi Ashique Ahmed Rafi

it usaully occurs in CDMA when users are transmitting unequal powers.

Generically, it's an 'overcurrent'; specifically, it's a 'short-circuit current'.

A high current flows through a short circuit even if there is no voltage change because the resistance across the short circuit is zero.

Series resonance occurs when a circuit's inductive reactance is equal to its capacitive reactance. The resistance of the circuit is irrelevant.WebRep

Tri-State: typically the 3rd state of a digital signal, floating (neither driven to a logic 1 or a logic 0).

Only a 555 can replace a 555, there is no equivalent. 555s are made by many companies, each with their own prefixes and suffixes, but all are 555s.
