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.
Illustrate ‘tan A ‘and ‘tan B' positions of a deflection magnetometer. Illustrate the theory to calculate magnetic moment of a bar magnet and Horizontal component of the earths
Null experiment: An experiment that yields no result after being executed. Null experiments are just as meaningful as non-null experiments; if current theory determined an obs
A reversible power cycle receives energy H Q from a reservoir at temperature H T and rejects C Q to a reservoir at temperature C T. The work developed by the power cycle is used to
The magnetic field of Earth resembles the field of a bar magnet. The north pole of a compass needle, used for navigation, generally points toward the geographic north pole.
How many types of fibers are there? There is truly only one fiber optic. The word "fiber optics" applies really to a stem of light physics dealing along with the properties of
Transformer cores are laminated with (A) Low carbon steel. (B) Silicon sheet steel. (C) Nickel Alloy steel. (D) Chromium sheet steel. Ans: Transformer co
Reflection of a Pulse at a Fixed End Let's assume a pulse moving by a medium - perhaps by a rope or a slinky. What happens to the pulse while it reaches the end of that medium?
The temp gradient is similar to finding the slope of a line (when in two dimensions) Temp. Gradient= Change in Temp. value/Distance. dT/dx = (T2 - T1)/(X2 - X1)
Printing Paper Industry: Synchronous motors are used in grinders. DC drives are used for pumping pulp and refining it.
