Numerical basis on star to delta and delta to star conversion...

What is the π-network and T-network??? And some important points..

     Hello frnds,.
In this video I will explain you about π-network and T-network ..
And also tell you two important points about star to delta and delta to star conversion..
            

Star to delta conversion..

 
         

Delta To Star Conversion with full explanation

Norton's theorem

Thevenin theorem

This video is very helpful for all ..

In this video I discuss about thevenin Theorem with examples..

Which bulb is glow brighter ???

WHICH BULB WILL GLOW BRIGHTER ?

(In Series and Parallel Connection)

When bulbs are connect in series

                

Example#1

 When a 200w, 220v Bulb (B₁) is connected in 

series with 100w, 220v (B₂) bulb across a power supply (Vs), which bulb will glow brighter ?

Solⁿ : 100w bulb is glow brighter than 200w bulb.
