Unit 2 Physics notes!!
Here's a question..in a circuit, if the resistance of a component increases, we say that the voltage dropped across it increases...why is that?? -
Physics Unit 2 Doubt!!!!
Oh..so using that resistance also gives about 12, right? That's where I got confused..okay thanks!! :) -
