How many different kinds of metal can electromagnetism pick up and at what voltage?
Certain materials are strongly magnetic, such as nickel, iron, cobalt, and their alloys. Whether or not a particular electromagnet can pick up a particular piece of metal (assuming it in one of those on the list) depends on the size and weight of the metal and the strength of the electromagnet. http://en.wikipedia.org/wiki/Magnetism

Low voltage does not imply low hazard?
This depends on your definition of hazard, and low voltage for that matter. A car battery is 12 volts, which is not enough to kill someone, but it is certainly enough to melt metal if you drop a metal tool across both positive and negative terminals. The melting metal can cause burns, etc.
Why current transformer should be grounded?
If there is a short circuit between the transformer's high-voltage windings and its core (or any other metal parts, come to that) the fault will be recognised by the high-voltage supply's protective system, which will quickly disconnect the high-voltage line. For this to happen, the metal parts of the transformer, including its core and metal container, must be earthed or grounded to provide an electrical path back to the source of the high voltage.
What is the purpose of ballast in lighting?
The ballast is a transformer that steps the voltage up higher than its incoming voltage. This is usually used with flourescent, metal halide, & sodium vapor lights. The higher voltage is needed to 'excite' the gases within the bulbs and make the molecules bounce around and give off light.
Why power rating of capacitor is reactive in nature?
A capacitor is composed of metal plates. Voltage is applied to one, which causes electrons to build up on the other. This is reactive in nature, thus a capacitor is reactive. It stores a charge, and releases this charge when the voltage decreases.
What is the voltage in your area?
Honey, the voltage in my area is typically around 120 volts for residential homes. But sweetie, make sure to check with your local utility company for the most accurate information. And remember, safety first, darling!

What are the 3 kinds of element?
The 3 kinds of elements are metal, non-metals, and metalloids.
What is the voltage of the metal crossbar?
The voltage of a metal crossbar would depend on the electrical circuit it is a part of. In an electrical circuit, voltage is the potential difference between two points and is measured in volts. If you provide more context or details about the circuit, I can help determine the specific voltage of the crossbar.
