This is Boolean rule#11. (It is not complete I know). My Q is, how did the

develop in the equation in line 4?rule #10 A = A + AB

rule # 7 A = AA

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)."

should be the formula to solve the series part, but how to solve the parallel R2 with Xc2?

Based on electron flow (neg to pos) current is flowing.

Lets say the swich is moved to #2 position instead of #1.

I cannot figure out what is happening with the current in this RC circuit. Im guessing current would start from VS to R3 then to R2.

Is there a trick to keep from confusing the

in the numerator and the denominator for each formula?Voltage divider formula in series.

Current divider formula in parallel.

Thx, it is more clear now.

Here is a separate Q.

I want to type in this angular formula on calculator. How do I go about inputing "rad?"

Why do you have to go; 1 divide 10 exp-3 to get the the answer in proper units.

The -3 is exponent.

If I go; 10 * 10^1 = 100

If I go; 10 exp 1 =100

I thought yx and exp were the same thing.

10 yx 1 = 10 on calculator but 10 exp 1 = 100

Never mind, I solved it. It is now correct

what am I doing wrong?

ok thx I get it

If I use the full method, I get the correct answer but this seems long process.

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.
