The resistance of a conductor depends upon?
2.inverse as cures of cross section of wire
3.material of wire
4.all of the above
Answer:
well resistance(R=V/I) involves voltages(V=Edl) and current. current(I=nAuE)involves the area of the wire, electron mobility, density, and the electric field acting on the wire. so from that you can determine that the length of the wire is necessary along with material of the wire(that involves the electron mobility) so all of the above would be the correct answer.
Magic 8 ball says "4 most definately"
all of the above
inverse as cures of cross section of wire
resistance, R is give by rl/A
r = resistivity
A = cross sectional area
l = length of wire or material used
so it shud be 1 2 and 3
therefore answer is 4
4.ALL OF THE ABOVE
#4. The longer the wire the greater the resistance. The greater the x-section of the wire, the lower the resistance (like a small pipe is more restrictive). And certainly copper has a lower resistance than many other materials. rgb
length of wire.. true
cross section of wire.. true
material of wire.. true
so all of above...
its, all of the above.
u wanna know how it depends on all of these??
ask me any time
we have talk about resistance of conductor it depends on the material of wire means depends on free orbits less valancy more resistance also on the width of wire (inverse)
ans is #4
R depends on all the three,ie length , area and material..
4.All of the above
length of wire,material of wire
4.All of the above
4 all the above
