In some instances, the groom's family will pay for the rehearsal dinner costs. It is also common for the groom's family to pay for tuxedo rental for the groomsmen. But none of these are rules per se. Talk it over with each family to see what works best for you.
Electrical Units of Measure. The standard SI units used for the measurement of voltage, current and resistance are the Volt [ V ], Ampere [ A ] and Ohm [ Ï ] respectively.
The ohm (symbol: Ï) is the SI unit of electrical impedance or, in the degenerate case, electrical resistance. An ohm is a resistance that produces a potential difference of one volt when a current of one ampere is flowing through it.
