Notice: Function _load_textdomain_just_in_time was called incorrectly. Translation loading for the accelerated-mobile-pages domain was triggered too early. This is usually an indicator for some code in the plugin or theme running too early. Translations should be loaded at the init action or later. Please see Debugging in WordPress for more information.

A Transformer Connected To A 240Vr.m.s Has 3000 Turns In Its Primary Coil And 500 Turns In Its Secondary Coil. Calculate The Output Voltage. - Erudites Academy

A. 4000V
B. 400V
C. 40V
D. 4V

Explanation

Np=3000turns
Ns=500turns
Ep=240Vr.m.s
Es=?

Ns/Np=Es/Ep
500/3000=Es/240

⟹Es=240×500/3000=40V
