A Meter Bridge is also called as slide wire bridge and is an instrument that works on the principle of a Wheatstone bridge. A meter bridge is used to find the unknown resistance of a conductor as that of in a Wheatstone bridge.

The newton-metre (also newton metre; symbol N⋅m or N m) is a unit of torque (also called moment) in the SI system. ... The unit is also used less commonly as a unit of work, or energy, in which case it is equivalent to the more common and standard SI unit of energy, the joule.

The newton-metre (also newton metre; symbol N⋅m or N m) is a unit of torque (also called moment) in the SI system. One newton-metre is equal to the torque resulting from a force of one newton applied perpendicularly to the end of a moment arm that is one metre long.

The working principle of voltage ELCB is quite simple. One terminal of the relay coil is connected to the metal body of the equipment to be protected against earth leakage and other terminal is connected to the earth directly.

Principle : It is based on the principle of production of dynamically (or motionally) induced e.m.f (Electromotive Force). Whenever a conductor cuts magnetic flux, dynamically induced e.m.f. is produced in it according to Faraday's Laws of Electromagnetic Induction.

rarmstrong. Sunil, you are correct about the difference between AF and metering. The camera's metering system is taking readings of the specific point you have focused on and set the aperture and shutter speed to get the best exposure. When you move the camera, what it "sees" in terms of light from the scene, changes.

When the XLPE cable breaks down during operation, M meter is used to measure the resistance, which is low; DC power source is used to “burnthrough” the fault, and the insulation resistance becomes higher and higher. In other words, leakage current tends to be normal value and hide the fault.

Working Principle The working of DC motor is based on the principle that when a current carrying conductor is placed in a magnetic field, it experiences a mechanical force. The direction of the mechanical force is given by Fleming's Left-hand Rule and its magnitude is given by F = BIL Newton.

Working principle of physical balance : ​A beam balance works on the principle of moments according to which in equilibrium, the anti-clockwise moment due to the weight of an object on left pan of the beam is equal to the clockwise moment due to the standard weights on the right pan of the beam.

['The meter read can be read from left to right, including all leading zeros. If a dial appears to be between numbers, record the lower number - except when the dial sits between 9 and 0, note down 9.', 'If your meter has two readings marked with an L and H, read both, left to right.']

How Does it Work? The typical HF SWR meter works by sampling the complex voltage and current at the point of insertion from which it calculates the effective SWR at the point of insertion on a transmission line with a characteristic impedance of 50 ohms (or whatever impedance for which the SWR meter is designed).
