The way to solve this is apparently to use division by the common factor which is 3x^2
However, if I solve it with out the division like this (see below), I get the same answer. So what rule should I be following? Am I skipping steps or am I using different method?
The question asks, what is the average value of the output voltage fro the circuit.
The choices are; 5.48v 2.74v 0v and 6.37v
I choose 6.37v using a simple formula; 2(160)/pie then divid by 16. Also tried accounting for .7v through diode, however, the book says the answer is 5.48v. Could the book have made an error with their answer?
Here is a question example out of text. Is the area correct? (I wasn't able to fill in the formula because of latex errors).
"What is the inductance of a 2 cm long, 150 turn coil wrapped on an low carbon steel core that is 0.5 cm diameter? The permeability of low carbon steel is 2.5 x10-4 H/m (Wb/At-m)."
Sorry, I added this to the original post before your reply:
My method is this: Divide the numbers first, then move the decimal three steps to the right in order to convert to milli amps. What rule am I not following in mathematics?
Yes 1000 ohms resistor or 1K.
