Assume you are given two resistors with resistances R1=4.0 kΩ and R2=6.0 kΩ and two capacitors with capacitances C1=4.0 µF and C2=6.0 µF.

a) Calculate the equivalent resistances Req and the equivalent capacitance Ceq if the resistors are connected in series and the capacitors are connected in parallel.

b) Now, use the Req and Ceq that you calculate in part (a) to construct an RC circuit. If an emf of 27 V is suddenly applied across Req and Ceq, calculate the current through the Req after t = 12 µs.

c) If the resistor R1 is made of iron wire with radius R= 3 mm, calculate the length of this wire. The resistivity of iron is ρiron= 9.68x10-8 Ω.m.

d) If the capacitance C2 has square parallel-plates with the separation of 0.3 mm, calculate the plate area A.

Assume that you have a box of resistors that have a Gaussian distribution of resistances with mean µ = 100 Ω and standard deviation σ = 20 Ω (i.e., 20% resistors). Suppose that you wish to form a subgroup of resistors with µ = 100 Ω and standard deviation 5 Ω (i.e., 5% resistors) by selecting all resistors with resistance between the two limits r1 = µ−a and r2 = µ+a. (Apparently, you are too cheap to just order the...

If three resistors with resistance of R1, R2, R3 are wired in parralle, their combined combined resitance R is given by the following formula: 1/R= 1/R1 + 1/R2 +1/R3 The design of a voltmeter requires that the resitance R2 be 80 ohms greater than the restance of R1, that the restance of R3 be 5 ohms greater than R1, and that their combined restance be 10 ohms. Find the value of each resistance. R1=________ohms R2=________ohms R3=________ohms
