Answer:

12 volts

Explanation:

The voltage ratio is equal to the turns ratio.

secondary/primary = 20/200 = v2/120

v2 = 120(20/200) = 12

The secondary winding voltage is 12 volts.

Answer:

The explanations are provided below.

Explanation:

a) The accelerated thermal cycling test is a test that is performed to evaluate the fatigue strength of electronic solder connections. The glass transition temperature given as $T_{g}$ is a frequently used parameter to test the degree of cure of an epoxy encapsulant.

b) The Coefficient of Thermal Expansion of Encapsulant

This is an important parameter to prevent crackling. Crackling occurs when a joint is subjcted to high temperatures during reflow soldering. Thus, the property is important in determining the limits of the joint.

1) Find the time in seconds to reach full charge in an RL circuit with L = 5 H and R = 100 ohms

pav-90 [236]

The time constant to reach full charge in an RL circuit is 0.05 ms.

Explanation:

To find the time constant,

The time constant for an RL circuit is defined by τ = L/R.

The given data is

L= 5 H

R= 100 ohms

by using the formula,

τ = L/R

= 5/100

= 0.05 ms

τ = 0.05 ms

Thus, the time constant to reach full charge in an RL circuit is 0.05 ms.
