FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF BACHELOR OF SCIENCE IN ELECTRICAL ENGINEERING OCTOBER 2010 I. INTRODUCTION An analog multimeter is a device that is composed of various meters combined. Such instrument can measure resistance‚ voltage and current. It is commonly known as volt-ohm meter or VOM. This device can also determine the continuity in a circuit and it measures with high accuracy. In this project‚ a VOM was built using the given parameters and tested it in various circuits

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 Chapter 6 Practice Problems 18. Determine the value of load power (PL) for the circuit

regulate the voltage supply‚ given to electronic circuits. This project‚ namely VARIABLE VOLTAGE REGULATOR‚ aims at fulfilling such small goals‚ using the 3-terminal voltage regulator LM317. The circuit consists of an IC LM317 and a set of resistors and capacitors‚ in addition to the transformer and the rectifying element. The AC voltage‚ from the mains supply is initially stepped down to the desired voltage‚ which is then rectified to be applied to the input terminal of the voltage regulator

Low-dropout regulator From Wikipedia‚ the free encyclopedia Schematic of a low-dropout regulator A low-dropout or LDO regulator is a DC linear voltage regulator which can operate with a very small input–output differentialvoltage.[1] The advantages of a low dropout voltage include a lower minimum operating voltage‚ higher efficiency operation and lower heat dissipation.[2] The main components are a power FET and a differential amplifier (error amplifier). One input of the differential amplifier
