Solution

The correct option is A 38.6
As you know, $W = Z . I . t$

$∴ 96500 \times 3 = Z \times 2.5 \times 50 \times 60$

$∴ Z = \frac{3 \times 96500}{50 \times 60}$

$Z = 38.6$

The correct option is A 38.6As you know, W=Z.I.t∴96500×3=Z×2.5×50×60∴Z=3×9650050×60Z=38.6

The correct option is A 38.6
As you know, $W = Z . I . t$

$∴ 96500 \times 3 = Z \times 2.5 \times 50 \times 60$

$∴ Z = \frac{3 \times 96500}{50 \times 60}$

$Z = 38.6$
