Question

A. Draw the complex circuit described below

A 12 volt emf source connected in series with R1 (3Ω) , in series R1 there are R2 (2Ω) and lamp 1 (4Ω) which are in parallel with each other. Connected in series with that parallel loop is another parallel loop, which includes on one branch , R3 (5Ω), R4 (2Ω) and Lamp 2 (3Ω) in series, and on the other branch of this parallel loop is R5 (7Ω), After that parallel branch there is a 20Ω resistor (R6) which is in series with all other components.

B. Calculated the follow from the circuit

a) Determine the equivalent resistance of the circuit?

b) What is the current for the entire circuit?

c) The current in resistor 4

d) The potential difference in lamp 2

e) The current for resistors 2,3, 4, 5

f) The potential difference for resistors 2, 3, 4, 5

Answer 1

Answer 2

A particle of mass m has a charge of magnitude q and is traveling with speed v in the +x direction. The particle enters a region of uniform magnetic field directed out of the page, and follows the path along the quarter-circle arc as illustrated. (a) (15 points) If the particle travels a total distance s along the arc while in the magnetic field, find an algebraic expression for the magnetic field strength B in terms of m, q, v, s, and pure constants. (b) (10 points) If the particle were to enter the same magnetic field region along the path shown to the right, what total distance d would it travel while in the magnetic field? Express your answer in terms of m, q, v, and s. Draw a sketch of the path followed by the particle in this case.
