And your answer to question 1 is incorrect decimal in wrong place, Answer = 0.7234 (I bet if you look at calculator 723.4 has a 10-4 to top right of answer.
Question 2. answer correct this is how I got it 100,000,000 / (2 x 3.142 x 20000 x 220) = 36.1715 ohms
The 100,000,000 represent convertion of 1/10-9 |
That is one way of doing it but very easy to make a mistake. You really need a calculator with an exponent key (ie. exp, ee) depending on your make and model.
