Question
1.
In a battery-powered circuit, current results from
electrons accelerating in response to an electric field.
positive ions accelerating from the positive battery terminal.
smaller electrons ricocheting off of larger positively charged particles.
positively charged ions attraction to the negative battery terminal.
2. In the circuit diagram, the current that the 20V battery conducts is:
-8A
2A
zero
-2A
8A
A.electrons accelerating in response to an electric field.
B.positive ions accelerating from the positive battery terminal.
C.smaller electrons ricocheting off of larger positively charged particles.
D.positively charged ions attraction to the negative battery terminal.
24 Y ? 3A 11 90 2? 4 6? 5 A T20 Y 9 4Explanation / Answer
1) A) correct. Free electrons are accelerated by the electric feild caused due to potential difference by battery.
B)&D) incorrect. No positive ions are displaced in a metal conductor. However in an electrolytic conductor positive and negative ions are displaced.
C) It happens inside the conductor however it is not responsible for current.
