What is Electrical Resistivity? Electrical resistivity is a property of materials and is different from electrical resistance which is a property of a component. Resistivity is also known as Specific Electrical Resistance or Volume Resistivity. Resistivity can also be defined as the inverse of the conductivity of a material - Ï = 1 / Ï.It is a measure of how a material opposes the flow of electric current. The SI unit of resistivity is ohm meter (Î©.m). Resistivity, Ï (Greek letter rho), is defined as:
For about the same price as a train ticket, you can take a Greyhound bus from Miami to New York. The trip takes about 32 hours, and you can go direct or stop in a city such as Richmond, Virginia or Orlando, Florida. If you book 3 weeks or more in advance, you can get a one-way ticket for under $100.
From LGA, the least expensive way (and often the fastest) to Manhattan is via the Q70 bus, or the Q48 or M60 buses. Basic fare is $2.75 per person. You will need to use coins or buy a MetroCard in advance of getting on the bus, because city buses do not accept bills.
