Question

Consider Example 22. Takin the coefficient of friction, mu to be 0.5, calculate the maximum compression of the spring.

Answer 1

Answer:

In a transformer, the number of turnsin the primary coil is 140 and that in the secondary coil is 280. If thecurrent in the primary coil is 4A, thenthat in the secondary coil is.

N1/N2 = I1/I2

I2 = N1*I1 / N2

= 140*4/ 280

= 2 Ampere

Answer 2

In a transformer, the number of turnsin the primary coil is 140 and that in the secondary coil is 280. If thecurrent in the primary coil is 4A, thenthat in the secondary coil is.

N1/N2 = I1/I2I2

=N1*I1 / N2

= 140*4/ 280

= 2 Ampere
