DC to AC Inverter Assignment # 2/ Spring 2013 CE721 Ahmad Ghaffari‚ 1203840 Submit Date: Tuesday 19‚ 2013 Abstract DC-AC inverter is a device that converts a direct current (DC) into an alternating current (AC). When there is no AC main power for applications in caravans‚ remote area and etc.‚ this tool is very suitable to use. It mainly converts a DC source (like a car’s battery) to an AC source (230V) to use for power application like

Permanent magnet (PM) direct current converts electrical energy into mechanical energy through the interaction of two magnetic fields. One field is produced by a permanent magnet assembly; the other field is produced by an electrical current flowing in the motor windings. These two fields result in a torque

Investopedia explains ’Leverage’ 1. Leverage can be created through options‚ futures‚ margin and other financial instruments. For example‚ say you have $1‚000 to invest. This amount could be invested in 10 shares of Microsoft stock‚ but to increase leverage‚ you could invest the $1‚000 in five options contracts. You would then control 500 shares instead of just 10. 2. Most companies use debt to finance operations. By doing so‚ a company increases its leverage because it can invest in business

Question 1. At this point‚ is this an outbreak? Why or why not? (2 points) According to the scenario this is an outbreak‚ because the case has occurred over a prevalent area without an efficient point source. This outbreak has occurred in a high-risk environment; local community centre; where it is common for individuals to experience a little as a flu. Also‚ it’s an outbreak because most outbreak occurs when clustered of unrelated individual experience symptoms around the similar time period‚

operates at either the 900 MHz or 1800 MHz frequency band. Mobile services based on GSM technology were first launched in Finland in 1991. Today‚ more than 690 mobile networks provide GSM services across 213 countries and GSM represents 82.4% of all global mobile connections. According to GSM World‚ there are now more than 2 billion GSM mobile phone users worldwide. Since many GSM network operators have roaming agreements with foreign operators‚ users can often continue to use their mobile phones

A DC motor is a mechanically commutated electric motor powered from direct current (DC). The stator is stationary in space by definition and therefore so is its current. The current in the rotor is switched by the commutator to also be stationary in space. This is how the relative angle between the stator and rotor magnetic flux is maintained near 90 degrees‚ which generates the maximum torque. DC motors have a rotating armature winding but non-rotating armature magnetic field and a static field
