For the second set of resistors in parallel, their equivalent resistance Rf = 1/16+1/19= 35/304, and flipping this upside down yield 304/35 Ω. The total circuit resistance is found by summing the 304/35 Ω and 168/50Ω. This amounts to 12.0446 Ω.
d) The Pd across each of the two resistors in parallel in parallel is found by subtracting 6.69446V from 24V. This equals to 17.306V. Therefore, using ohms laws, the amount of current through the 19 Ω resistor is V/R= 17.306V/19 = ...Download file to see next pagesRead More

### Women in mathematics,Science,and Engineering

...? The role of women in careers which revolve around math, science and engineering has been a central concern of democratic societies around the worldas those societies have attempted to extend social and economic equality. Because math, science, and engineering careers are among the most powerful and lucrative professions in the information age, most advanced governments and societies have believed it important to ensure that women are encouraged to enter those fields and that they have access to the careers in them through proper education and certification. In this paper, the status and role of women in math, science, and engineering in Canada will be reviewed in order to determine how successful one of the most developed... of such...

### Women in mathematics,Science,and Engineering

...Women in Mathematics, Science, and Engineering Women employees with skills in science and technology are an essential resource today, in leading knowledge based economies, such as in the OECD countries. Due to the rapidly growing technology, there is an acute demand for science and technology employees, with the job growth being motivated and driven by an increased number of female employees in this sector. However, women are highly underrepresented in science and technology studies at the secondary and tertiary levels of education, and in the overall technical workforce. This is despite evidence that suggests further involvement of women in technology...

### Engineering Science

...Engineering Science Assignment III Compare the actual resonant frequency obtained from the graph with thecalculated value. Using the formula, the calculated value of the resonant frequency is 1/ 6.283 * 10-3 = 159.2 HZ. Due to limitations in the resolution of the measurement equipment, the table indicates a band of frequencies where the maximum current seems to indicate resonance. However, we can approximate the frequency of resonance from the chart by finding the median frequency of the peak current values for each value of R. R=0 Median Frequency = 155 HZ R=500 Median Frequency = 155 HZ R=1000 Median Frequency = 160 HZ R=1500 Median Frequency = 160 HZ The measured values from the table were all within...

### The Triangle of forces (Engineering Science)

...The Triangle of Forces (Lab Report) Science Practical Assignment Faculty January 22, 2009 Aim: The aim is to verify experimentally the theorem of the triangle of forces. Introduction: The theorem of the triangle of forces states that “if three forces P, Q, R (See Figure 1) meeting at a point can be represented in magnitude and direction by the three sides of a triangle OB, AO, and BA respectively, taken in order, then the three forces are in equilibrium.” Figure 1: Triangular force diagram In above diagram (figure 1), actually, the converse of the triangle of forces theorem is investigated, that is “ if three forces P, Q, and R meeting at a point are known to be in equilibrium, then their magnitude and directions can be...

The relationship between the density, volume and the mass is shown in the equation below: Volume = Mass x density Or Q=m / ρ -------------------------------------------------------------- 1 For any volume flow, the speed depends on the pipe cross-sectional area. The link between the volume and the cross sectional area is shown n the equation 2 below.
