Edexcel PHYSICS Doubts
The Golden Girl =D:
but they didn't state the motion of the plane in the question, so u they assumed it moved forward ( as in the to Right) , is that right or am I just blabbing?
astarmathsandphysics:
Planes do fly forward. Do you mean the voltage?
Use the left hand rule - it is upwards as you drew it in the diagram.
The Golden Girl =D:
I meant it's direction of Motion. The arrow I drew was the direction of the induced e.m.f which is the opposit of resistance so how did we know the direction of motion of the airplane even though it wasn't stated in the Question , so you simply assumed that it moved forward right? and secondly ,why did the direction of induced e.m.f turn out that way :S (Pink arrow that is in the diagram I drew )
This topic sure does confuse me =[
can u explain in detail (perhaps a diagram could help) thanks sir =]
astarmathsandphysics:
The direction of the current is upwards sorry. The current is always taken as positive, but the current is actually carried by negatively charged electrons, which move downwards.The electrons will flow towards the positive terminal so the positive termainal is at the bottom and the negative at the top.
The Golden Girl =D:
Sorry for asking too many Questions but how did you know that Current is Upwards :$
