What happens to the voltmeter when the lamp is unscrewed in a circuit?
Like in a normal circuit with a:
Batt, Lamp, Switch, ammeter, and a Voltmeter.
And another question:
What’s the relationship between the Potential Difference (voltmeter) and the bulb’s brightness?
Please answer this ASAP!
I need this quick!!
Thanks! (:
Oh yeah, I also meant the voltmeter is parallel to the lamp.
