The resistance is 2.50 k 2. a) Calculate the inductance of the circuit 14) In the combination circuit shown below, you are given several resistors that are connected in various ways. a) Find the equivalent resistances of the circuit given the following values for the resistors (using series and parallel): b) What is the current? SHOW ALL WORK... OR NO CREDIT 492 519 MR so 7522 mü R. 45 4 15) In the mirror shown below, the angle of incident is 22º. normal P P OR mirror c) What is the angle of reflection equal to?

Solve. clear handwriting. Thank You!

Answer 1

are 2 9 R42 = 49+51 2 = 10o2 3) Metals that can can be ma magnetized iron , Nickel, cobalt, Gadolinium, 14) Rg and R₃ are in series so Rq3 R4 RE so R45 Ry and Rs are in parallel RytRo Rus 37 x 45 82 R45 = 20.32 in series Rube R4152 = 20.3+75 R456 = 95.32 R45 and Ra

R456 and Rigs are in parallel Rg3456 95.3 X 100 195.3 R93456 = 48082 in series so are R 93 456 and R, R123456 80+48.8 = 128.82 v v current 198.8 R 15) Angle Angle of reflection is equal to angle incidence o. OR of э Б 29° OR

please rate it up thanks :)
