3 You are working in a lab building resistor circuits and you
realize the project you have been assigned requires a precise 1%
tolerance 17.0? resistor. The closest you can find is a 16.9?
resistor. You try contacting your labs supplier to order the
resistor only to find out the 16.9? at 1% tolerance is as close as
they manufacture. You're supervisor has an excess supply of 10.0?
1% tolerance resistors and instructs you to construct a resistor
circuit comparable...

_________m
(b) What will be the diameter of the wire?

Suppose you have 5H inductor and 10-ohm resistor, if you
were to change the resistor to 500ohm, how would the graph of
current vs time be different from the 10-ohm resistor and would the
current "settle" as same, higher, or lower value as 5H? (Please
provide graph).

(HW11-31.14) You have a 230-? resistor and a 0.380-H inductor.

The voltage across the 30-k? resistor in the figure (Figure 1)
is measured with (a) a 90-k? voltmeter, (b) a 400-k? voltmeter, and
(c) a digital meter with 40-M? resistance. To two significant
figures, what does each read?
Va= ________ V
Vb=_______ V
Vc=_________ V

You are given a 44 kΩ resistor, a 1.5 kΩ resistor, and an
unmarked, “mystery resistor”. You are told that the mystery
resistor has an impedance somewhere between 5,000-6,000 kΩ. You can
only accurately measure resistances less than 1,000 kΩ.
i) How would you build a Wheatstone Bridge to determine the
exact impedance of the mystery resistor? One resistor will need to
be a variable resistor. Build the circuit and submit an image and
URL to your circuit
ii) What...

Suppose you have an RLC series circuit constructed using a
resistor with a non-zero resistance, an inductor with non-zero
inductance, a capacitor with non-zero capacitance, and for which
the voltage lags the current. How could you get this circuit to
resonance by varying only the capacitance of the capacitor (it’s a
variable capacitor)?
Group of answer choices
a) Decrease the capacitance of the capacitor.
b) Increase the capacitance of the capacitor.
c) Actually, only varying the capacitance of the capacitor...

Exercise 1.Suppose the color code on a resistor is yellow,
violet, orange and gold. What is its resistance and what is the
uncertainty of this resistance?
Exercise 2.Suppose you purchase a nominally 100 Ω resistor from
a manufacturer. It has a silver band on it which signifies a 10%
tolerance. What does this mean?
Exercise 3.A piece of wire of resistance? is cut into 5 equal
lengths.These parts are connected in parallel. How does the joint
resistance of the parallel...

You have a 150-? resistor, a 0.400-H inductor, a 8.00-µF
