Question

Rectangular loop is rotating about z-axis, at 500 rev/min. Then find the current in loop. Where R = 0.20 W and B is in radial outward direction and its value is 0.2 T.

• A. 0.523 A
• B. 0.319 A
• C. 2.369 A
• D. 1.235 A

Answer 1

Answer: (A)

0.523 A

Answer 2

e₁ = B × 0.5V₁

e₂ = B × 0.5V₂

i = =

= $\frac { 0.2 \times 0.5 \{ 2 \times \pi \times 500 ( 0.05 - 0.03 ) \} } { 0.2 \times 60 }$

= $\frac { 0.5 \times 2 \times \pi \times 500 \times 0.02 } { 60 }$ i = $\frac { 25 \times 0.02 \times 3.14 } { 3 }$

i = 0.523 A
