Answer:

The answer is below

Explanation:

1.5 - kΩ resistor is connected to an AC voltage source with an  rms voltage of 120 V. (a) What is the maximum voltage across  the resistor? (b) What is the maximum current through the  resistor? (c) What is the rms current through the resistor?  d) What is the average power dissipated by the resistor?

Solution:

The rms value of current and voltage shows the alternating quantity of the voltage and current.

Given that V(rms) = 120 V, R = 1.5 kΩ

a) The maximum voltage across the resistor is given as:

V_{max}=\sqrt{2}*V_{RMS}\\\\V_{max}=\sqrt{2}*120\\\\V_{max}=169. 7\ V

b) The maximum current through the resistor is:

I{max}=\frac{V_{max}}{R}\\\\ I{max}=\frac{169.7}{1.5*10^3}\\\\I{max}=0.113 \ ohm

c) The rms current through the resistor is:

I{rms}=\frac{V_{rms}}{R}\\\\ I{rms}=\frac{120}{1.5*10^3}\\\\I{rms}=0.08 \ ohm

d) The average power dissipated by the resistor is:

P_{av}=\frac{V_{rms}^2}{R}\\\\ P_{av}=\frac{120^2}{1500}\\\\P_{av}=9.6\ W

How much power is used if a force of 54 newtons is used to pull a wagon a distance of 10 meters in 6 seconds?
AnnZ [28]
First, calculate the work done: 54 x 10 = 540J.
Now calculate power: 540 / 6 = 90.
The answer is 90W.

Hope this helps.

Quinn accelerates her skateboard along a straight path from 0 m/s to 4.0 m/s
umka2103 [35]
  • initial velocity=u=0m/s
  • Final velocity=v=4m/s
  • Time=t=2.5s

\\ \sf\longmapsto Acceleration=\dfrac{v-u}{t}

\\ \sf\longmapsto Acceleration=\dfrac{4-0}{2.5}

\\ \sf\longmapsto Acceleration=\dfrac{4}{2.5}

\\ \sf\longmapsto Acceleration=1.6m/s^2
