Homework Week 6 Chapter 5 Practice Problems 15. Determine the potentiometer setting required to set the total circuit current in Figure 5.32a to 50mA. I1=Vs/R1= 12V/300Ω= 0.04 x 10^-3= 40mA I2=It – I1= 50mA – 40mA= 0.01 x 10^-3= 10mA R2=Vs/I2= 12V/10mA= 1200 x 10^3= 1.2kΩ 38. Figure 5.43 shows a potentiometer wired as a current divider. Determine the values of Rab and Rbc that will provide values of I1=4 mA and I2=6 mA. Rab= (4mA/10mA) x 100Ω= .4 x 100Ω= 40 Ω Rbc= (6mA/10mA) x 100Ω= .6 x 100Ω= 60Ω

DC Circuits: Electric Power PHY 114 Lab Report 10/09/2013 Abstract: The purpose of this experiment was to look at electric power dissipated in a load resistor in a circuit with a real power source‚ which has a finite internal resistance. We discover a surprising result about how to deliver the most power to a device from a source. Consider a simple circuit in which a battery of voltage drives a current through a resistor of resistance. As we have seen‚ the battery is continuously doing

Working with the 555 555 is used for producing a clock (square wave) at a desired frequency. It can be used in various ways like the astable mode‚ monostable mode etc. Here‚ we deal with the astable operation of 555. Astable mode ensures that the 555 is self-triggered & so‚ it acts as a multi-vibrator. Let us look into the working of 555 in astable mode: These are the connections needed to make the 555 chip run in the ‘astable’ mode. The pin numbers are given in circles. Note the

Alternating Current RC and LRC Circuits Lab 7 November 12‚ 1012 109989- 5:30 PM Abstract Within this experiment we recorded that the theoretical capacitance of 0.470 is accurate with the capacitor from box C. The LRC circuit is proven to have a voltage accurate with the measured generator voltage because the largest percentage of error ‚ 0.55 % error‚ is much lower than 5% error. Summary The idea of the alternating current RC and LRC circuits lab is to record the value

The primary focus in this essay will be addressing the question: how can an issue be an ethical concern if it does not directly endanger human life or society? This is particularly important as in contrast to other branches of engineering‚ the moral issues surrounding electrical engineering do not usually affect a consumer’s health or lead to injury or death.

network for supplying this electrical power is known commonly as the National Grid. The National Grid is an electric power transmission network which connects the substations and power stations. This is so that any electrical energy generated in Great Britain‚ can be utilized and help meet energy demands elsewhere. This grid system also includes interconnections that run under the sea to Northern Ireland HVDC Moyle‚ the Isle of Man and France HVDC Cross-Channel. The electrical energy generated for the

Electrical Conductance and Insulation OVERVIEW: Every thing in the world is differentiable on the basis of its electrical conductance. Some things are called insulators and these substances never conduct electricity. they include things such as cold air‚wood and plastic. Then there are things that conduct electricity and current flows through them‚ they are called conductors. examples of conductors are most metals like copper and steel. Other materials that are sometimes used as conductors are
