For most mom-and-pop eateries and even many franchise owners, getting to just $1 million in revenue is a dream. The average fast-food restaurant brings in just over $750,000, the National Restaurant Association reports.
P1-RC, 12. 1  P1 means Passenger 1. 2  RC means the status of reservation is RAC (Reservation against cancellation) 3  12 means that passenger 1 is 12th in line for confirmation against cancellation of ticket by other passengers.
A first order, low pass RC filter is simply an RC series circuit across the input, with the output taken across the capacitor. We assume that the output of the circuit is not connected, or connected only to high impedance, so that the current is the same in both R and C. The voltage across the capacitor is IXC = I/ÏC.
