If you change the length of a resistor how does the current through a circuit change?

Answer #1

You have a cylindrical 20 Ω carbon resistor (ρ=5x10-5
Ω m) that is 1.0 cm long and has a cross section area of 0.1
mm2. The resistor is connected to a 5 V battery.
Part 1: What is the resistance of the resistor if its area is
doubled?
Part 2: By what factor does the power dissipated by the resistor
change if the resistor length is halved and the battery voltage is
doubled?
Part 3: By what factor does the...

1) An AC circuit is constructed with just a resistor connected.
If the frequency of the circuit increases, how does the average
power dissipated across the resistor per cycle change compared to
when the frequency was lower?
2) A 60 V battery is connected in series with a 30 ohm resistor
and a 10 H inductor. How much time will it take for the current to
increase to 1.5 A?

ANSWER ALL 4 QUESTIONS PLEASE
1-You have set up an LRC series circuit and are observing the
voltage drop across the resistor on an ideal oscilloscope. If you
disconnect the oscilloscope, does the current in the circuit
change? Why or why not?
2-When a line light source with spectral lines is observed
through a diffraction grating
I. the blue lines are closer from the center than the red
lines.
II. the blue lines are farther from the center than the...

(11 pts) You arrange two wires, a resistor, and a metal bar to
form a complete circuit like the one on the right. The resistor has
a resistance of 54 Ω. You place the circuit inside a uniform
magnetic field of 0.64 T that points into the page. There is no
source of emf in this circuit when the bar is not moving.
a. (3 pts) The bar has a length of 0.14 m and is 0.23 m away from...

What is a competitive market? Describe and give an example. 2.
Does a change in consumer tastes cause a movement along the demand
curve or a shift in the demand curve? Explain.

Hello! Does a Resistor decrease the current , if so how come the
current entering a resistor is equal to the current leaving the
resistor ? Thank You

a) If you have one resistor in series (R1) and two resistors in
parallel (R2 and R3), what value of R3 would make the effective
resistance of the circuit equal to R1 and why does that work?
b) If the effective resistance of the same circuit is 5kOhms,
the length is 0.03m and width is 0.02m and we power the circuit by
making the B field increase by 5T every second, what is the current
in the circuit. Include both...

(HW11-31.14) You have a 230-? resistor and a 0.380-H inductor.
Suppose you take the resistor and inductor and make a series
circuit with a voltage source that has a voltage amplitude of 26.0
V and an angular frequency of 300 rad/s .
A) What is the impedance of the circuit?
B) What is the current amplitude?
C) What is the voltage amplitude across the resistor?
D) What is the voltage amplitudes across the inductor?
E) What is the phase angle...

Give an example of a ternary cyclic code of length 8
and dimension 5.
Explain why the example is valid.

-Give an example of an experiment from your field of study where
a pattern in data is used to construct a mathematical
relationship.
-Discuss how plotting data can help you identify the
relationship between the current through the resistor and the
potential difference across it.
