Question

What Is The Difference Between Isolation Transformers And Step Up Or Step Down Transformer?​

Answer 1

Step-down transformers have fewer secondary turns than primary turns, while step-up transformers have more secondary turns than primary turns. Isolation transformers have equal turns in both windings.

Answer 2

Answer:

Actually an isolation transformer may be physically the same as a Step up/Step Down transformer. The main difference is in the way they are used.

Another difference is that in a normal transformer there will be capacitance between the 2 windings, between the windings and core, between the core and shell, etc.

These capacitances bring in high frequency noise from outside, which will be transmitted in the secondary circuit. So [in an isolation transformer] wires are connected between each component, (not direct contact, but with insulation present). This permits a leakage current and eliminates unnecessary capacitance.

Shaft power P = (2(pi) * (angular Speed in rpm) * (Torque at shaft))/ 60

Torque of a solid shaft is given by (pi/16)* (Shear stress of material of shaft) * (Dia of shaft3)

Question 50. What Is Free Fall Acceleration?

Answer :

On earth free fall acceleration is 9.81 meters per second per second or 32.2 feet per second per second, not including air resistance.

Around these parts, free fall acceleration is the acceleration due to earth gravity on a body that is not acted on by an outside force (like air resistance or a bungee tether).
