### Q: What does a capacitor look like at high frequency?

5 respuestas

A: A capacitor looks like a capacitor, inductor, and resistor in series at high frequency. Menos

A short

Its an short circuit at very high frequencies. Look at the impedance for a capacitor and you'll notice that the frequency is inversely related to it. (also note that capacitor impedance is purely reactive). Therefore, as frequency increases the impedance approaches 0, which acts like a short. (an inductor is the opposite) Menos

### A boat is in a swimming pool and there is a rock in the boat. What happens to the level of water if the rock is thrown out of the boat?

5 respuestas

Any rock that will have the density less than water?... It will fall because due to Achimedes' Law the total bouyant force decreased, hence so it is with the volume of space occupied below the water level. Menos

It depends on the ratio of volume of the rock vs the displacement of water. This is dependent on the density of the substance. In the boat it should displace a volume of water greater than the volume of the rock since the density of the rock is greater than the density of the water. Once in the water it should displace only it's own volume which do to it's density is less than the water it had to displace while in the boat.; hence, the water level decreases. Menos

It depends on the density of the rock If the rock sinks: the water level actually falls....think about it...but this is the right answer. Menos

### what is your marks (%age) in last semester?

4 respuestas

I have answered what i have got.

70%in 8semester

I’m pursuing my engineering from G H Raisoni Collage Of Engineering, Nagpur , Maharashtra, I’m studying in 3rd in Electrical Engineering and my self Vishal Deshmukh .. I have 68% in 10th because I represent Maharashtra in National Kabbadi Turnament so that reason behind my low percentage in 10th and my pointer from 5th sem is 8.20 and SGPA from 2nd year is 8.89 so I can eligibal for your company Menos

### How would you know if an electric motor is bad without connecting to power?

5 respuestas

Explain the motor resistance test.

Motor resistance test:This test is an important measurement/test because it detect some of the problems other test/measurement couldn't, it is easy with the use of "motor circuit analysis" winding resistance test detects various faults in motors such as shorted and open turns, wrong turn count, wrong wire gauge, some connection mistakes, resistance balance between phases, short to ground. Menos

Aside the physical observation for burnt and smell of the coil also the colour appearance of the coil and rust, an ammeter will be used to check winding of the phase to determine if there short circuit or shunt in each winding,which implies continuity . The cone or ammiture should be tested ,component test for resistivity and inductance will be tested. Menos

### Why did you choose an Engineering

4 respuestas

Engineers are problem solvers. I'm good at problem solving, so choosed engineering! Menos

Engineer only makes a world change the world so I really proud to be an engineer

doctor advocate engineers are professional degree.. what we study well work related to that most of them dont no this engineering quality Menos

### What is power factor?

3 respuestas

Power is cosine angle between current and voltage

mathematically cos of the angle between voltage and current physically the angle measure the active and reactive power . the reactive power back to the source again , the angle measure that value Menos

the power factor of an AC electrical power system is defined as the ratio of the real power absorbed by the load to the apparent power flowing in the circuit, and is a dimensionless number in the closed interval of −1 to 1 Menos
