They are exactly analogous to water pressure and water flow by a hose. That's why flowing electrons is known as a current, just like a water current.
Voltage is the electromotive force (the force to move electricity) that needs to push electrons by a wire the way that water pressure (which we could call the hydromotive force by analogy) is the force that needs to push water molecules by a hose.
The wire and the hose each offer resistance to the force. Less resistance or more pressure (force) means more flow, whether that be gallons/minute of water or amperes of current.
Factors on which Magnetic Force Depends: The magnetic force depends on following factors: 1. Nature of Pole: Like poles repel each other and unlike pole attract each other.
A cylinder having 1.00 g of water at the boiling point is heated until all the water turns into steam. The expanding steam pushes a piston 0.365 m. There is a 215-N frictio
Q. Find the electric potential at a distance 0.09 m from a charge of 4 X 10 -7 C. The electric potential V = ( 1/4πεo ) q /r = ( 9 X 10 9 X 4 X 10 -7 )/ 9 X 10 -2 = 4 X 10

Explain Crohn disease Crohn's disease: a chronic, recurrent disease characterized by patchy inflammation of any portion of digestive tract from the mouth to anus.
It is the force that the field would exert on any unit magnetic pole placed in the field. It is also known as magnetic force.
