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

Abraham Lincoln did not truly believe that races were equal. At a speech in Springfield‚ Illinois‚ he openly says that in some respects‚ a black woman is “certainly not my equal” (3). Here he is focusing more on the fact that she is black rather than that she is a woman‚ but either way‚ he sees himself as more superior that her. But in respect to human rights‚ he believes that she does have her‚ for example‚ “natural right to eat bread [that] she earns with her own hands” (3). She is his equal and

Sakib Khan Electric Eels – Physics The animal that is usually known as electric eel is in fact not really an eel but a freshwater species related more to the carp family or catfish family. These unique freshwater predators got their name from the immense electrical charge that they can easily generate to stun or even kill their preys and dissuade predators. Electric eels can grow extremely large which usually can reach as high as 8 foot long and weigh a great amount of 45lbs. In addition to this

However‚ more manufacturers are developing ’plug in’ Hybrids‚ which offer the option to recharge more powerful batteries through a common household electricity socket. Hybrids are environmentally friendly One main reason drivers opt for a Hybrid over a standard car is that they want to cut the impact their motoring has on the environment. These motors are more

ELECTRIC DISCHARGE MACHINING INTRODUCTION * Sometimes it is referred to as spark machining‚ * Its a manufacturing process whereby a desired shape is obtained using electrical discharges (sparks). * Material is removed from the workpiece by a series of rapidly recurring current discharges between two electrodes‚ separated by a dielectric liquid and subject to an electric voltage. * One of the electrodes – ‘tool-electrode’ or ‘tool’ or ‘electrode’. * Other electrode - workpiece-electrode
