Which wire will be connect at NO or NC contact?
NO stands for Normally Open and NC is Normally Closed. It references a switching application. It is the base state of the switch. So if the load is connected to the NC terminal it will usually be energized and when the switching device is activated the circuit will open and the load will be de-energized. The NO terminal would have the load de-energized until the switch was activated and then it would be energized.
If air resistance is negligible then terminal velocity is the velocity of shock waves?
If resistance is negligible, then there is no terminal velocity.
How does air resistance affect terminal velocity?
Without air resistance, there would be no such thing as terminal velocity.
What does common mean on a light switch?
On a single pole single throw there is no common terminal. On a single pole double throw it is the terminal that is common to both the top and bottom terminals. The "hot" wire is connected to the common terminal so that when the switch is in the up position that terminal becomes energized and there will be no no voltage on the bottom terminal. When the switch is in the down position the bottom terminal becomes energized and there will be no voltage on the top terminal. In relays thisis known as a C form configuration.
What is the difference between the terminal voltage and the source voltage?
the source voltage is the voltage that measured exactly after the voltage source , but the terminal voltage is the voltage that measured in the load terminals , which equal to the source voltage minus the drop voltage on the transmission line .
What effect terminal velocity and air resistance have on a sky diver when he opens his parachute?
Air resistance increases and terminal velocity decreases when the parachute has opened.
What is the speed an on object reaches when the force of gravity is balanced by air resistance called?
terminal velocity
What do you get when you subtract the force from resistance from the force of gravity?
Terminal Velocity
What is it called when air resistance and gravity are the same?
Terminal Velocity
Why is terminal velocity an example of balanced forces?
When terminal velocity is reached, the gravitational force is balanced with the force of resistance.
Why is the terminal velocity in water less than the terminal velocity in air?
More resistance, caused by a greater density.
What happens when the primary winding is energized and the secondary winding is open circuited?
A voltage appears between the terminal points of the secondary winding
