supposed to be MOSFET.
but i also depends on your working freq.
A MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) can be used as a load by operating it in its linear region, where it behaves like a variable resistor. By controlling the gate voltage, the MOSFET adjusts the current flowing through it, thus allowing it to regulate power in circuits. This application is common in battery management systems and motor control, where precise control of load characteristics is essential. Using a MOSFET as a load offers advantages such as high efficiency and fast switching capabilities.

A MOSFET (metal oxide semiconductor field effect transistor) can be used INSTEAD of a BJT (bypolar junction transistor, so transistor is redundant in your question), if the circuit in question is modified to allow it and the MOSFET is chosen appropriately. BJT's will usually have a higher intrinsic gain, but have lower input resistance. Also a BJT in general will work better at higher frequencies than a MOSFET (unless you choose a high frequency MOSFET) due to the capacitive nature of MOSFETs.
Using ordinary multimeter A1-A2 should show high or infinite resitance in both ways, G-A1 low ohms, less than 100r
The basic difference is between JFET and enhanced MOSFET,although the construction of JFET and depletion MOSFET is different but their most of the characteridtics are same,i.e shockly equation can be applied on both of them,but in JFET we cant give to gate voltage, the +ve value,because it does not works, but in depletion we can give,but some limited +ve value. Now enhanced MOSFET is different,shockly equation cant be applied.The transfer characteristics are purely in +ve Vg region. i.e for E-MOSFET Vg should be > 0,for its proper function.
MOSFET has high input impedance and offer input signal isolation from the circuit
Yes
Triac.
high speed drill bits

it can exchange the current is much larger and has Avery low resistance when it is turned on.the mosfet is not removed from the circuit when the supply is on because it flow the high current.
mostly high speed switches in digital logic circuits
The size of high speed pressure varies greatly based on how it is measured and the application it is used in. Some high speed pressure houses measure less than an inch while others may be several inches in diameter.
The SiO2 layer acts as an insulator and also it provides high input impedance to the MOSFET. This insulation is needed so that a circuit with high EMI or loads which generate back emf (motors) can be driven by applying gate current from a common circuit.

yes.
High speed steel is made from different steel alloys. Depending on the application and budget the alloy is made from iron and different mixes of carbon, tungsten, cobalt, chromium, molybdenum, and vanadium.
