Chapter 26: Q75P (page 770)

A certain x-ray tube operates at a current of 7.00mAand a potential difference of 80.0kV. What is its power in watts?

Short Answer

Expert verified

The power of an X-ray tube is 560W.

Step by step solution

01

The given data

  1. Potential differenceV=80kVor80×103V
  2. Current, i=7mAor7×10-3A
02

Understanding the concept of the power

The power of an X-ray tube can be calculated by taking the product of the current and potential difference.

Formula:

The equation of power that occurs due to potential difference, P = iV (i)

03

Calculation of the power

Using the given data in equation (i), we can get the power of an X-ray tube as follows:

P=7×10-3×(80×103)=560W

Hence, the value of the power is 560W.

Figure-agives the magnitude E(x) of the electric fields that have been set up by a battery along a resistive rod of length 9.00mm(Figure-b). The vertical scale is set by. Es=4.00×103V/mThe rod consists of three sections of the same material but with different radii. (The schematic diagram of Figure-bdoes not indicate the different radii.) The radius of section 3 is 2.00mm. (a) What is the radius of section 1 and (b) What is the radius of section 2?

A 30 μFcapacitor is connected across a programmed power supply. During the interval from t = 0 to t = 0.300s the output voltage of the supply is given byV(t)=6.00+4.00t-2.00t2voltsvolts. Att=0.500s find (a) the charge on the capacitor, (b) the current into the capacitor, and (c) the power output from the power supply.

Near Earth, the density of protons in the solar wind (a stream of particles from the Sun) is8.70cm-3 , and their speed is 470 km/s. (a) Find the current density of these protons. (b) If Earth’s magnetic field did not deflect the protons, what total current would Earth receive?

Figure 26-19 shows four situations in which positive and negative charges move horizontally and gives the rate at which each charge moves. Rank the situations according to the effective current through the regions, greatest first.

If the gauge number of a wire is increased by 6, the diameter is halved; if a gauge number is increased by 1, the diameter decreases by the factor 21/6 (see the table). Knowing this, and knowing thatof 10-gauge copper wire has a resistance of approximately, 1.00Ω, estimate the resistance of 25 ftof 22-gauge copper wire.
