When a potential difference of 10 V is placed across a certain solid cylindrical resistor, the current through it is 2 A. If the diameter of this resistor is now tripled, the current will be:.A) 18 A. B) 2/3 A.
C) 3 A.
D) 2/9 A.
E) 2 A.

answer: the answer is a

b mirrors submit a iisner? e. for which optical devices does d sometimes have a positive value? o a a and b o b. a and c o c. b and d 0 d. b and cb

need to see circuit to get time constant

the assestment will probley apele with cause and effect
