a) equal and opposite
b) -charge on A, + charge on B
Vb > Va so negative
c) electrons
the electrons move through the wire from A side to B side
BUT
the current is defined as if it were positive charges moving through the wire
SO current through resistor from B side to A side
A charged capacitor (AB) carries on its plate A a charge Q=-1.2mC
a) What is the charge carried by plate B.
b) Is the voltage U (AB)=V (A)-V (B) positive or negative.
c) The plates A and B are connected to the terminals of a resistance R: the capacitor gets discharged.
What are the charge carriers which move in the connection wires. What is the direction of the transitional electric current
