What doesnot cause the height of mercury column to vary?
change in the value of g
Under what circumstances can an object move in a circular path without being accelerated?
It can't. If there is a change in direction, there is a change in velocity ("velocity" includes the direction), and therefore, an acceleration.It can't.

What is DC Energy?
That may refer to DC electricity - direct current. This is when the current always flows in the same direction, unlike AC which changes its direction several times per second.That may refer to DC electricity - direct current.

What causes a spaceshuttle to change in velocity by change in direction?
A change in velocity constitutes a change in direction because velocity includes direction.
What is a DC charge?
DC = direct current, it is a steady charge that keeps going the same direction. AC = Alternating current, it is a charge that changes direction very quickly. The positive and negative keep switching.
What change occurs in flux when load increases in DC shunt motor?
no change occurs because the flux is controlled by the supply and not the load on the generator. thus flux doesnot change unless the supply changes
How do you change the direction of DC motor?
by changing the ryb phase altornat e.g. rby ,bry , yrb we change the direction of the induction motor .. . ..
How can you rotate the dc series motor in both direction?
in any dc machine changing the polarity of the field will change its direction. here, in series motor, the field is in series with the armature, to which we feed the supply. hence, change the feeding polarity.
What is D-C electricity?
DC electricity is direct current, compared to AC which is alternating current where the current is consistantly changing direction, direct current does not change direction. The main source of DC is a battery.
What is the difference between AC machine and DC machine?
ac machines can run only in one direction but dc machines can run in both the directions depending upon the direction of current flow into it. If we change polarity of input supply we can reverse the direction of motion of dc machineCommentThe above answer isn't altogether true, as it's very easy to change the direction of an AC machine. For example, to change the direction of rotation of a three-phase induction motor, the motor controller interchanges two of the three line conductors.The main difference used to be that the speed of DC machines is easier to control, but that is a thing of the past thanks to developments in electronic motor controllers.
Why Dc welding sets are prefered over AC welding sets?
Often because with DC, it is possible to change the direction of the weld current for the task at hand.
Electrically how is AC different from DC current?
DC is direct current, current travels in one direction. AC is alternating current, current changes direction twice per cycle. 60 Hertz would change direction 120 times per second.
How does a diode change from AC to DC?
it clips all the bottom voltage off the sine wave,to get steady dc voltage you will need to clean up the ripple to get good voltage regulation <><><> A diode does not change AC to DC, but it does allow alternating current to flow in only one direction. A diode (or often 2 or 4 diodes) with a filter can be used to rectify AC into DC.
What is he past tense of quiet?
The past tense of "quiet" is "quieted" or "quietened."
Which doesnot change when spherical mirror is broken?
Its radius of curvature and its reflecting property
What doesnot cause the height of mercury column to vary?
change in the value of g
Can diode work on ac power supply?
diodes conduct electricity in only one direction but as ac change direction in each of its cycle diodes can only conduct half of its cycle which will give u a pulsating dc. but if dc is mixed with ac and if it can put whole of its cycle in positive direction diode can conduct ac. so diodes are usually used to produce dc from ac.
