Time constant

Physics Lab: RC Circuit Lab Emma Chen January 5, 2015 Team members: Alex Wang, Andy Val_ 1. Objectives The objective of this lab is to create an RC circuit that has a time constant of 10. 2. Method and Principle: The RC circuit that we created on the breadboard was a series circuit. RC circuits contain resistors and capacitors, and are connected to a voltage source. In our case, this voltage source was the battery. When we were measuring the voltage on the computer, we used a switch instead

measure the charging and discharging abilities of a resistor capacitor circuit. In a RC circuit the voltage is an asymptomatic function of the charging time. If a battery were connected in series in a circuit with a resistor, there would be a constant current. In contrast, if the battery were connected with a capacitor in series, the current would be time-varying, decaying to zero as the capacitor charges up. The results of the experiments verified the properties of the RC Circuits, confirming that

More mean, and less standard deviation indicate more important factors (Rahman, 2014) relating to the propensity to save. On the basis of the table no.2, it is clear that ‘to have enough social security” is the most important factor to the propensity to save (Mean 3.78, and SD 0.91). Then takes place for ‘children education’ (Mean 3.72, and SD 1.15), and ‘to get good interest’ (3.71, and 0.81). To be rich man is in the 4th place for cause of human saving. Reliability and Validity Test: The right

while maintaining the output current ripple within a pre-defined range. To study the impact of VSFPWM on switching loss reduction over the entire modulation index range, the simulations were carried out different speeds (modulation indices) for a constant load torque. Table II and Table III compares the current ripple, and the percentage change in the current distortion and the switching losses for CSFSVPWM-VSFSVPWM and CSFDPWM2-VSFDPWM2 techniques respectively. Similar to the analytical results at

ROLL NO. = G2015CODPOO7 SEMESTER= second semester Anything that has a measurable characteristic that varies is variable which may change from group to group, a person to person, or even within one person over time. To understand more precisely of what is variable we will deal with the two types of concepts: those that refer to fixed phenomenon and those that vary in quantity, intensity, or amount. The second concept and measures of the concept are variables

Often times as researchers, we will take continuous variables and break it up into categories, typically for the purpose of grouping, or to measure an outcome measure. We usually decide on a reasonable cut-point and place the data in the appropriate category. Streiner (2002) asserts that this categorization results in lost information, reduced power of statistical tests, as well as an increased probability of a Type II error. In Streiner (2002) article, written primarily for researchers, he states

Sensitivity Analysis-Colectomy, CABG, and PCI Multiple analyses were conducted to test the sensitivity of price regression results: 1) HHI measurement by different definitions and levels; 2) GLM regression using different distribution families; and 3) non-linearity of age, HHI, and HMO penetration. HHI Measured by Admissions vs Inpatient Days The main GLM regression models included a hospital admission HHI where the total number of admissions in a hospital is measured as a proxy of the hospital’s

the scientific method are defining a problem, forming a hypothesis, collecting research and data, conducting the experiment, and defining the conclusion. Fine tuning is the precision of the physical constants of nature, as the beginning of the universe requires extremely precise values. These constants serve to explain the nature of the universe, theories that potentially point to a divine creator. Evidenced through the initial conditions of the universe, such as the expansion energy and rate of
