According to the pattern of half-cell potentials what determines the polarity of a cell?
According to the pattern of half-cell potentials, what seems to determine the polarity of a cell?
How can the shape of a molecule determine it's Polarity?
A symmetrical molecule cancels out the effects of polar bonds.
What is the formula to determine wft?
what is formula for coil coating WFT formula
How does molecular shape effect polarity?
The molecular geometry of a compound helps to determine polarity because, it indicates the number of lone pairs on a central atom thus giving it specified angles and polarity (only if there are lone pairs because if there are no lone pairs on the central atom, them it is non-polar).
What is the difference between an AC and DC generators?
AC generator, the brushes run on slip rings which maintain a constant connection between the rotating coil and the external circuit. This means that as the induced emf changes polarity with every half-turn of the coil, the voltage in the external circuit varies like a sine wave and the current alternates direction. DC generator, the brushes run on a split-ring commutator which reverses the connection between the coil and the external circuit for every half-turn of the coil. This means that as the induced emf changes polarity with every half-turn of the coil, the voltage in the external circuit fluctuates between zero and a maximum while the current flows in one constant direction
What rule is applied to find the polarity of the face of a current carrying circular coil?
in physics
In what two ways can the rotation of a shunt connected dc motor be reversed?
DC shunt motor can be reversed by changing the polarity of either the armature coil or the field coil.

Can you connect pressure coil instead of current coil in watt meter to measure power?
You have to connect both coils to measure power: the current coil in series with the load, and the voltage ('pressure') coil in parallel with the supply. And you have to observe the wattmeter's polarity markings if you don't want it to read downscale (backwards)!
How can the shape of a molecule determine it's Polarity?
A symmetrical molecule cancels out the effects of polar bonds.
How do you produce a current with a magnet and coil of wires?
Move the magnet up and down through the centre of the coil. The quicker it is moved the higher the voltage generated. When the magnet moves towards the coil it generates current with one polarity and when withdrawn the current reverses in polarity. This is described in Fleming's left hand rule. The voltage generated can be increased by adding more turns of wires to your solenoid. All electricity from any type of power station is produced in this way.
What is the formula to determine wft?

How do you determine if the motor starters are properly earthed?
by magnetisation of no voltage coil
When connecting power supplies that convert ac to dc note that the diode will determine the load polarity?
This statement is correct
How does molecular shape effect polarity?

What lets the north pole and south pole of a solenoid be able to change poles?
The poles of the solenoid depend on the direction of the current through the coil. The current reverses if you just reverse the polarity of the voltage between the ends of the coil. Heck, if you energize the coil with AC, you can do that 120 times every second.
Why the polarity of transformer is important?
a polarity test is a test which use to check the polarity of tranformer.the rision of this test to running the two or more transformer in parallel.like bettry situation or to fin the terminals
