We know that AD is the shortest way but ABCD is connected in series
Equivalent Resistance =R1+R2+R3
=(10+10+10)ohm
=30ohm
Since BC and AD is connected in parallel
1/Req=1/R1 + 1/R2
=1/30 + 1/10
=3+1/30
=4/30
So, Req=30/4 ohm
Now,Current drawn from the battery
=> I = V/R
=> I = 30/4 ohm/3v
=> I = 30/4*3
So, I = 10/4 A

The correct option is C.
From the information given above, one can easily conclude that electromagnetic Y is the strongest because, it produces the higher amount of current compare to the other electromagnets. Electromagnet W is the weakest because it produces the lowest amount of current.
Answer:
E = 1.25×10¹³ N/m²
Explanation:
Young's modulus is defined as:
E = stress / strain
E = (F / A) / (dL / L)
E = (F L) / (A dL)
Given:
F = 10 kg × 9.8 m/s² = 98 N
L = 1 m
dL = 10⁻⁵ m
A = π/4 (0.001 m)² = 7.85×10⁻⁷ m²
Solve:
E = (98 N × 1 m) / (7.85×10⁻⁷ m² × 10⁻⁵ m)
E = 1.25×10¹³ N/m²
Round as needed.
