Which statement is true of ac current? . select which statement is true of ac current? . select one of the options below as your . a.. it uses a battery as a power source.. b.. it can easily be transformed from high voltages to low voltages.. c.. it is typically low voltage.. d.. the electrons are moving in one direction. e.. it was the first type of electric current invented..one of the options below as your

B.. It can easily be transformed from high voltages to low voltages..

Explanation:

As we know that transformers are based upon the principle of Faraday's law of electromagnetic induction.

As per the above principle EMF is induced in the closed loop if flux linked with the coil changes with time.

So here we can say

so here when we use AC current in transformers then it can be transformed into higher voltage or lower voltage as per the requirement because it will change the flux linked with the coil.

so correct answer will be

B.. It can easily be transformed from high voltages to low voltages..

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j
