What is the period of the voltage waveform out of a wall outlet?
60 seconds
What is a TVSS in Electrical Engineering?
A TVSS is a transient Voltage Suppression System. It activates in times of a high voltage condition. The high voltage condition could be caused by many things such as a lightning strike or a transformer failure.
Why does the speed of the DC series motor rise to a run away condition if full voltage is applied while there is no load?
At no load, the speed of a series motor rises to a run-away condition if the full voltage is applied because the applied voltage appears directly at the terminals of the motor and drives it to a run-away condition since speed is proportional to the voltage.
Can you connect an AC source in series to DC source - then what happens to the current under a steady state condition?
With an AC and a DC voltage source in series, the DC voltage can be added to the RMS value of the AC voltage to give the effective voltage.
How to control the high voltage control in an industry?
Voltage stabilisers are the devices to control voltage. These are of 3 types i.e. VARIAC BASED,IGBT BASED and THERMISTOR TYPE. These are classified according to voltage correction speed i.e. from 70 volt/second to 750 volt/seconds.

Which condition refers to a sudden and dramatic increase in voltage which usually caused by lightning?
Surge voltage, voltage step, voltage spike
Why does the speed of the DC series motor rise to a run away condition if full voltage is applied while there is no load?
At no load, the speed of a series motor rises to a run-away condition if the full voltage is applied because the applied voltage appears directly at the terminals of the motor and drives it to a run-away condition since speed is proportional to the voltage.
Why voltage in transformer suddenly increases and then decreases suddenly?
In perfect condition, the voltage variations does not occur.. Due to failure causes, voltage variations will arise
How would you fix a starting problem in an opel astra g 2001 model?
It takes a lot of voltage to turn a starter, even if everything else works. Typically between 9-11V. First get a cheap voltage tester and check batt voltage when off. If ok, check condition of cable and at end of cable. Start there
What mechanism should be adopted to keep terminal voltage constant in varying loading condition in an alternator?
Voltage Regulator
Which condition refers to a sudden increase in voltage?
That would be 'spiking'
What is the condition when voltage drop occur when motor running?
its lose
How a zener diode is used in voltage regulator under both varying input and varying load condition?
In the varying input condition, the zener diode is used in such a that any variation in the input voltage,should not in any affect the load (that is the arrangement supplies just the voltage needed by the load no matter how high or low the supply voltage might go). In the varying load condition, the zener diode is connected in such a way that any change in the load voltage should not affect the input voltage.
Is it the value of input voltage equal the value of output voltage?
No. There are several factors that may affect the output voltage. For instance: Resistors, Transformer, Voltage regulators and others that can control the output voltage to a certain level.
What is the condition that prevent the current to pass across diode?
if the voltage across the diode is less than the cut-in voltage of that particular diode .
