1)
What is the principle behind Carey Foster Bridge?
Wheatstone's principle
Bernoulli's principle
Both (a) and (b)
None of these
2)
What is the relation connecting resistance and resistivity?
R=ρl/A
R=ρA/l
ρ=RAl
ρ=Al/R
3)
Carey Foster Bridge is used to measure
High resistance
Low resistance
E.M.F
All the above
4)
As the temperature increases, resistance
Decreases
Increases
No change
First increases then decreases
5)
In Wheatstone's bridge, P = 10 ohm, Q = 20 ohm R = 5 ohm, then value of X is
10
20
15
5
