Question:
An ideal transformer takes an ac voltage of amplitude 170 V as its input and supplies a 7.8 V amplitude to a circuit that converts it to dc. The primary has 300 turns.
(a) How many turns does the secondary have?
(b) When the circuit uses a power of 5.0 W, what is the amplitude of the current drawn from the 170 V line?

I graduated in 2018 with a Bachelor of Science degree in Psychology from Dalubhasaan ng Lungsod ng San Pablo. I tutored students in classes and out of classes. I use a variety of strategies to tutor students that include: lecture, discussions about the subject matter, problem solving examples using the principles of the subject matter being discussed in class , homework assignments that are directed towards reinforcing what we learn in class , and detailed practice problems help students to master a concept. I also do thorough research on Internet resources or textbooks so that I know what students need to learn in order to master what is being taught in class .
