What is the effect of the reverse bias on the width of the PN junction?
The holes and electrons move away from the junction and attracted towards the terminals as the positive polarity is connected to the n-side and negative polarity to p-side.
Does reversing the polarity of a DC motor damage anything?
Reversing the polarity of a DC motor will not inherently damage it, as most DC motors are designed to operate in both directions. However, it can lead to issues if the motor is under load or if it is not designed for bidirectional operation. Additionally, reversing polarity may affect the motor controller or driver circuitry, potentially causing damage if they are not rated for such operation. Always consult the motor's specifications and the control circuitry documentation before reversing polarity.
What is the equipment required to do a CT polarity test?
You shouldn't need to perform a polarity test on a CT, as its terminals are normally identified with polarity markings.
Which current is having high polarity?
ac(Alternating Current ) has the high polarity.
Does thermistor have polarity?
No, they have no polarity. They are just like a resistor in terms of polarity, and they allow to measure temperatures because their resistance varies with temperature in a predictable way.
What does negative polarity mean with electricity?
Polarity is the direction of flow of electrons throughout a circuit. There are two types of polarity: positive and negative. Postive polarity is of older circuits which means electrons flow from positive to negative. Negative polarity is of more modern circuits and that is the flow of electrons from negative to positive such as on car batteries
Is unequal sharing of electrons acidic basic or polarity?
Unequal sharing of electrons refers to polar covalent bonds, which involve atoms with different electronegativities sharing electrons unevenly. This polarity can lead to acidic or basic properties depending on the specific nature of the molecules involved.
What does the ( ) or (-) oxidation number tell you about an ion?
Its electric charge polarity. If (+) it is missing electrons, if (-) it has extra electrons.
What causes the polarity of a water molecule?
the unequal sharing of electrons
Does the nature of light effect the polarity of compound?
No, the polarity of a compound may however affect light.
What would happen if electrons went the opposite way?
If electrons went the opposite way they might change their polarity.
Describethe ways you can change the polarity of the molecule?
The polarity of a molecule can be changed by altering its molecular structure or the distribution of its electrons. This can be achieved through the introduction of electronegative atoms, such as chlorine or oxygen, which can create dipoles. Additionally, changing the geometry of the molecule, such as shifting from a linear to a bent shape, can affect how dipoles interact and thereby change overall polarity. Lastly, modifying the functional groups present can also influence the molecule's polarity.
What are factors affect the solubility of a substance?
Temperature and polarity.
Does boiling point affect the polarity of water?
Boiling point is not directly related to the polarity of water. The boiling point of water is determined by the strength of intermolecular forces between water molecules. Water is a polar molecule due to its asymmetrical shape and unequal sharing of electrons, which leads to hydrogen bonding and a relatively high boiling point.
What does electronegative mean?
Electronegativity refers to an atom's ability to attract and hold onto electrons in a chemical bond. Atoms with higher electronegativity values tend to attract electrons more strongly than those with lower values. This can affect the overall polarity of a molecule and its chemical reactivity.
How does the electronegativity affect the polarity of the bond of two atoms?
The more electronegative an atom is the more "pull" the atom will have on the electrons in the molecules. For example, water (H2O) contains the very electronegative atom Oxygen. Oxygen would pull more electrons toward it so the hydrogen would essentially lose their electrons. The dipole moment would point towards the oxygen. Therefore, the more electronegative an atom is the more the dipole moment will point in its direction therefore affecting polarity of the bond.
Which is described as a charge imbalance within a molecue due to unequal distribution of electrons?
polarity
