what electronic component is generally used to change the ac voltage into dc voltage in large dc motor controllers?
SCR because it can be controlled with reference to the point in the cycle at which it will turn on.
ote: this is a multi-part question. once an answer is submitted, you will be unable to return to this part.consider the given figure. knowing that the radius of each pulley is 200 mm, p
The calculated torque is 91.55 KN-mm. Yes, the radius of the pulley has an effect on the belt tensions.
For a given frictional torque at the axle, the tension difference between the pull side and the load side is smaller because a larger radius produces a greater moment.
Each pulley's radius is 50 mm;
R1 = R2 = 50 mm.
R1 = 50 mm for the driver's radius
50mm for the radius of the driven,
1800 for the angle of contact (in radians), and
0.3 for the coefficient of friction. T1 = 3KN of permissible stresses Always, T1 is bigger than T2.
Utilizing the formula T1/T2 = e After adding together all the values,
T2 = 1.169KN and 3/T2 = e(0.3)().
Because both pulleys' radiuses are the same, they both experience the same amount of torque (T1–T2). R1
= (T1–T2) (T1–T2). R2

The factors that is influenced performance of cooling tower are:
RangeHeat loadAmbient wet-bulb temperature or relative humidity.Approach.The temperature difference between the hot water inlet and cold water outlet at the tower is called a range. The temperature of tower's ambient is generally 4 ° C to 6 ° C (or even higher) less than the ambient temperature. Because of the temperature is cool, the cooling tower ready to cool the water at a temperature below ambient temperature. The impact of ambient temperature makes energy consumption increase.

technician a says that viscosity index improvers thicken oil when it becomes hot and thins it when it becomes cold. technician b says that viscosity index improvers thin oil when it's hot and thicken it when it's cold. who is correct?
Technician a is correct that he says Oil is thickened by viscosity index improvers when it is hot and thinned when it is cold.
The viscosity index (VI) is an arbitrary, unitless measurement of how much a fluid's viscosity changes as a function of temperature. It is mostly used to describe the behavior of lubricating lubricants' viscosity-temperature relationship. The more the viscosity is impacted by temperature variations, the lower the VI. The viscosity index is a way to quantify how viscosity changes in response to temperature changes. The viscosity index, to put it simply, indicates how well a fluid can maintain its viscosity throughout temperature fluctuations. An arbitrary scale known as the viscosity index is used to assess how quickly viscosity changes as temperature rises. The rate of viscosity change as a result of temperature change is measured by a lubricant's viscosity index (VI).
