Supply Delta


What is the capacitance of the capacitor?

A Capacitor is connected ti a 30.0 Hz power supply that produces an rms voltage of 90.0 V. What is the capacitance of the capacitor, if the maximum current is 110 mA?
The answer is 4.58uF but i am not sure how to solve

The relation between capacitance, current and voltage is:

I = C dV/dt

Try to go from there!

Compaq Pavilion


Which laptop is better for me: HP Pavilion or Compaq Presario?

I just want a decent laptop that can hold lots of pictures, fast, has at least 2GB of…i think RAM?, and cool looking…

Compaq computers in general are cheaper. They have always been bargain basement computers. I believe that HP bought Compaq, but they still have not gotten any recognition or “better” in that case. I would go with the HP if those are your only two choices.

Intel Laptop


Where can I find the model number for my Toshiba Intel Pentium laptop?

I accidentally tripped over the charger and my laptop fell off the table and the screen cracked. I don’t have the box so I can’t figure out the model, how can I find the model? Also, if this has happened to anyone is it possible to just buy a replacement screen?

it should be on the bottom of the laptop on a black and white sticker…cheers

Link Dvi


DVI-I single link adapter on DVI-I dual link video card… will it work?

So I was thinking of buying a new video card for my computer that only has a DVI-I dual link port… however I only have a VGA monitor and a single link DVI-I to VGA converter. I do not have the money to spare for another monitor, so I wanted to know if it will work. Will a single link adapter work with a dual link port? Thanks in advance.

Yes, it will work.

A DVI-I port can put out both a digital DVI-D signal and an analog VGA signal. That’s what that “-I” stands for– Integrated.

Hope this helps.
