Answer:

D) Electric power distribution.

Explanation:

Electric power distribution requires high voltages to efficiently transmit electric power. This requires use of a transformer which uses electromagnetic induction.

Answer:

D) Electric power distribution.

Explanation:

As we know that the Faraday's law of electromagnetic induction says that rate of change in magnetic flux linked with a closed conducting loop will induce EMF in the loop.

This induced EMF is used for power production so here when we use it for the production of voltage across conductor.

it is used in AC generator when a coil is rotated at high speed between strong magnetic field of magnets.

This is induced EMF is given by

EMF = NBA\omega sin(\omega t + \phi)

so here correct answer will be

D) Electric power distribution.

Why are household wall sockets alternating current (AC) instead of direct current (DC)? Select all that apply.
Bond [772]

Answer:

It is easier to scale the voltage of AC from high to low and low to high than with DC

Explanation:

typically power is used far away from the place where it's generated so to ensure that transmission losses( copper losses) are minimized voltage has to be stepped up during transmission..but due to the fact that most house hold equipment requires low voltage levels it has to be stepped down once it reaches a household/ domestic load...it's easier to do this for Ac than for DC.
