The minimum start current that will start a motor is a function of the load torque and motor design
Using the simplified per phase equivalent circuit of an induction motor, one can get the following equation of electromagnetic torque:
\[T_e= 3 \times \frac{I_r^2R_r}{s \omega_s}.\]
\[I_r = \sqrt{\frac{s \omega _s}{R_r}\times T_e}\]
\[T_e = J \frac{d\omega}{dt}+ T_l \]

Time they say is of the essence, so i decided to design this simple desktop clock to always remind me of the time. the unique features of this clock is it can be resize to any size, this make it easier to see from a far, it is always on top of other windows and there is no icon present at the taskbar.
Clock resize to small size
The Clock with size increased to some point

A rice cooker is an electrical machine which is use purposely for cooking rice. A simple rice cooker monitors the boiling point of water and take an action based on a set point.

Due to the poor efficiency of linear Power supply which uses a bulkier transformer(due to the lower frequency of the mains) and linear regulators to step down and regulate the input voltage respectively; switch mode power supplies was invented.
In a switched-mode power supply (SMPS), the AC mains input is directly rectified and then filtered to obtain a DC voltage.
The resulting DC voltage is Zakaria Mohammedhttp://www.blogger.com/profile/02006051902442806036noreply@blogger.com53tag:blogger.com,1999:blog-30999154475852234.post-15625376043817604512016-10-29T16:55:00.002+00:002022-09-06T19:27:38.703+00:00BASIC TIMING TRAFIC CONTROL USING PIC16F877A
