Can samone help with this

00:33:42

So i have a source of 10V and a resistor of 5Ohm. And i have a lightbulb of 20W

10V ÷ 5 Ohm = 2A 
2A × 10V = 20W

So why doesn't the lightbulb light properly

Your resistor lowers voltage to 5 volts before it reaches the light. Try removing resistor.

Head over to the examples page and check out the circuit titled "KCL and Current Divider". Read the description and play with the circuit to see what's going on..

You forgot the resistance of the bulb in your calculation.
