A square law device is a system or device that operates based on the principle of square law, which states that a physical quantity is proportional to the square of another quantity. In electronics, square law devices are commonly used in radio frequency circuits to control signal strength or amplitude. One common example of a square law device is a diode, which exhibits square law behavior in its current-voltage characteristics.

Why FET is called square law device?
A FET is called a square-law device because of the relationship of ID to the square of a term containing VGS.
What is square law diode modulator?
Methods of amplitude modulation can be put in the two categories namely Linear modulation methods and Square law modulation methods. Linear modulation method utilizes the linear region of the current voltage characteristics of the amplifying device that is transistor or electron tube. Square law modulation method utilizes the square law region of some current voltage characteristics of a diode or transistor or electron tube. A large number of linear modulation methods have been devised and have been used to varying degree. These methods are namely linear shunt plate modulation or anode choke modulation, linear series plate modulation, grid bias modulation, cathode modulation, suppressor grid modulation, screen grid modulation, collector modulation. Square law modulation circuits make use of non linear current voltage characteristics of diodes or triodes and are in general suited for use at low voltages. Important square law modulation methods are square law diode modulation and balanced modulator.
Is zener diode a linear device?
Zener diode is not a linear device... it is non-linear one. Since linear devices are those devices which have linear characteristics(V-I CHAR.), or follows the Ohm's law i.e. voltage is directly proportional to current. but in case of Zener diode ohm's law fails down. the V-I char. in both forward biased & reverse biased condition is non-linear. So. Zener diode is non-linear device
What is the current flowing through the first device of a circuit when the first device has a resistance of 12 ohms and the 2nd device has a resistance of 4 ohms circuit voltage is 40 volts.?
You describe a series circuit. This answer is for a series circuit. The total impedance is 16 Ohms, 12 + 4. The current by Ohm's Law (Amps = Volts / Ohms) is 40 / 16, or 2.5 Amps. Kirchoff's Current Law says that the current at every point in a series circuit is the same, so the current flowing into the 1st device, the 12 Ohm resistor, is 2.5 Amps.
In a series circuit each device that is added to the circuit decreases the what?
Depends on the device. If it is a resistor and you have a fixed voltage then the circuit will obey Ohms law. Voltage = Current x Resistance. So if R increases by adding more resistors in series and the voltage is constant, the current will decrease.

What is square law detection?
Square law detection is a method used in communication systems to demodulate analog signals. It relies on multiplying the input signal with itself to obtain the power of the signal, which contains information about the original signal. This method is commonly used in amplitude modulation systems for recovering the original message signal.
