500
You have a parallel circuit with 3 light bulbs and 1 switch. One of the light bulbs has fallen out but the switch is still on. Will the other 2 lights stay lit?
Yes! In a parallel circuit, a lights going out will not effect the other lights
500
What does Ohm's law describe the relationship between?
The relationship between current and voltage
