Assuming ideal conditions of course, resistance in wire = 0 etc.
As I understand, when 1) switches 4 and 5 are closed then bulb 1 will glow the same as if 4 was open, that means at 100W and bulb 3 will also be at 100W, bulb 2 will not work. The voltage drop across the bulbs will be 220V...
Hi guys.
I need some help with an assignment. I have a circuit as depicted below with a 220V AC power source and 3 100W lamps. I’m asked to calculate the power in each lamp when switch 4 is closed and when switch 5 is closed. I’m also asked whether the lamps are brighter or dimmer.
I’m...
