DevinThe AC Hall effect is used to measure the sign and magnitude of an alternating magnetic field, whereas the DC Hall effect is used to measure the sign and magnitude of a steady magnetic field. In AC Hall effect, the magnetic field changes direction periodically, while in DC Hall effect, the magnetic field is constant.

What is the phase difference between the current through the resistor and inductor in an AC circuit?
The phase difference between the current through the resistor and inductor in an AC circuit is 90 degrees.
What is difference between ac and DC bulb?
AC bulbs are designed to be used with alternating current, which constantly changes direction. DC bulbs are designed to be used with direct current, which flows in only one direction. Therefore, the internal workings and design of AC and DC bulbs are different.
What is difference between skin effect and franty effect?
The skin effect refers to the tendency of high-frequency alternating current to flow more on the surface of a conductor than through its interior. On the other hand, the proximity effect (often confused with the "franty effect") is an additional increase in resistance that occurs when multiple conductors carrying high-frequency currents are placed close to each other, leading to non-uniform current distribution.
When current increases in an ac circuit what roll dose inductance play?
Inductance creates a counteracting magnetic field that opposes the change in current, leading to an increase in reactance and a phase shift in the current waveform. This can cause a lagging power factor in the circuit and affect the overall impedance, affecting the circuit's behavior.
If 110 V ac is applied to the primary what is the output potential difference?
Assuming a 1:1 turns ratio in the transformer and neglecting losses, the output potential difference would also be 110 V AC.
