Answer:
Explanation:
We can find the resistance of the wire by using Ohm's law:
where
V is the voltage applied
R is the resistance
I is the current
In this problem, we know I = 6 A and V = 68 V, so we can re-arrange the equation to find the resistance of the wire:
Answer:
4.78 × 10⁻³ T.m²
Explanation:
The expression for the magnetic flux is given by
∅ = BAcosФ
where B = magnetic field strength
A = Area of circular loop = πr²
r = radius of the wire loop
substitute πr² for A in the first equation
∅ = Bπr²cosФ
∅ = 2.55 × 3.14 × 0.025² × cos 17.3°
∅ = 4.78 × 10⁻³ T.m²
OR
0.00478 T.m²
