When does steam turbine shaft suffer from hogging?
Hogging in a steam turbine shaft occurs when there is an uneven distribution of weight or thermal expansion along the shaft, causing it to bend or deform upwards at the center. This condition is typically exacerbated during startup or shutdown when temperature gradients are significant. If not addressed, hogging can lead to misalignment, increased wear, and potential damage to bearings and seals. Regular monitoring and alignment checks are essential to prevent hogging and maintain proper turbine operation.
Is the base current smaller or larger than the emitter current?
The base current of the emitter current is smaller.
The emmiter current of an n-p-n transistor is equal to?
The sum of (base current) plus (collector current).
What transistor current is always the largest?
In a bipolar junction transistor (BJT), the collector current (Ic) is always the largest of the three currents, which include the base current (Ib) and the emitter current (Ie). This is because the collector current is primarily influenced by the amplified current from the base, while the emitter current is the sum of the base and collector currents (Ie = Ib + Ic). In field-effect transistors (FETs), the drain current (Id) is typically the largest. Overall, in both types of transistors, the current flowing through the collector or drain is generally larger than that through the base or source.
Who collector base current when emitter is off?
When the emitter of a bipolar junction transistor (BJT) is off, the collector-base junction is typically reverse-biased, meaning that the collector current is minimal or negligible. In this state, the collector-base junction does not conduct significant current because the emitter does not provide carriers to the base. As a result, the collector current is effectively zero, and the transistor is in its cutoff region.

What is information hogging?
The meaning of hogging is keeping something away from other people. This leads to show that information hogging would be keeping information away from other people for viewing or knowing about it.
Why does collector current increase with base current?
the collector current is directly proportional to the base current

What is tax hogging?
Tax hogging is where Gordon Brown steels all the tax payers money and spends it on a nice villa in Florida.
Is the base current smaller or larger than the emitter current?
The base current of the emitter current is smaller.
Why the base current is responsible to turn on or off a transistor?
base current is very small and we should apply ainput on base current
