The picture shows a battery connected to two wires in parallel.
Both wires are made of the same material and are of the same
length, but the diameter of wire A is twice the diameter of wire
B.
True or False for the following:
1) The resistance of wire B is four times as large as the
resistance of wire A.
2) The power dissipated in wire A is 16 times the power
dissipated in wire B.
3) The voltage...
Potential difference between two conductors?
A coaxial cable consists of a long cylindrical conductor of radius a=1 mmconcentric with a thin cylindrical shell of larger radius b=5 mm. If the central conductor has a charge per unit length ?=Q/L=1 micro(C)/m uniformly distributed on itssurface, what is the potential difference between the inner and outer conductors?
