What are the two kinds electricity?
Perhaps you are referring to DC and AC? DC is direct current - current flows in a single direction. In AC (alternating current), the current regularly changes its direction.Perhaps you are referring to DC and AC? DC is direct current - current flows in a single direction.

Electric current changes direction repeatedly is called?
AC current (alternating current) like in a wall outlet
How both positive and negative half cycles of a ac voltage distributed through a single phase. can anybody please explain?
Single-phase ac has current that changes direction 100 times a second (if it's a 50 Hz supply). It only needs two wires to distribute a single-phase supply. Imagine it as a battery that is continually being reversed.
Is voltage negative or positive?
A negative or positive sign is applied to a current depending upon the direction in which it is moving, and in the case of alternating current, that direction changes 60 times per second. Viewed strictly as a form of energy, voltage is always positive. So far, physics has not detected negative energy.
Are staples required where cables run through holes in framing?
No, staples are not required where cables are run horizontally through holes in framing members. When the cable changes direction from horizontal to vertical runs from the last hole a staple is required, no greater distance that 16 inches from the hole.
How do you explain that the pencil appears broken in the glass of water?
A ray of light changes direction when it gets out of the water, and into the air. This is called "refraction".A ray of light changes direction when it gets out of the water, and into the air.

A fixed pulley changes the blank of a force?
changes the direction of a force
What are acceleration and velocity?
'Velocity' means the rate at which position changes, and the direction in which it changes. 'Acceleration' means the rate at which velocity changes, and the direction in which it changes.
What changes if somethings speed or direction changes?
If an object's speed changes, it means that it is either speeding up or slowing down. If an object's direction changes, its velocity changes as well, as velocity is a vector quantity that includes both speed and direction. These changes in speed and direction are typically caused by forces acting on the object.
Does a wedge change the direction of the force?
when it changes its direction
Explain why velocity changes while driving around a circular track even if the speed is constant?
While the speed may be constant, the velocity changes because velocity is a vector quantity that includes direction. As the car drives around the circular track, its direction constantly changes, causing the velocity to change even though the speed remains the same. This change in velocity is due to the centripetal acceleration required to keep the car moving in a circular path.
What is important because is changes food energy into a form all cells can use?
Explain how respiration is the opposite reaction to photosynthesis
What changes the direction of a force?
Force changes either the speed or the direction of motion, or both.
What changes if someones speed or direction changes?
If someone's speed changes, it means they are moving faster or slower than before. If someone's direction changes, it means they are now moving in a different path or route. Both changes can affect the individual's position, velocity, and acceleration.
Why is it important to explain foreseeable and unforeseen changes which may occur to children?
It is important to explain both foreseeable and unforeseen changes to children to help them feel safe, secure, and prepared. By being aware of potential changes, children can develop resilience and coping skills to navigate unexpected events. Additionally, open communication fosters trust and comfort, improving their overall well-being.
How can velocity change without changing the speed?
Consider velocity as consisting of a speed, and a direction. If any of the two changes - that is, if either the speed or the direction changes - then the velocity changes.
When electric current changes direction is called?
When electric current changes direction, it is called alternating current (AC).
