1" is equal to ______ cm - (answers)2.54 cm
1" is equal to ______mm - (answers)25.4 mm
Circumference Formula - (answers)C = 2πr
Area of a circle - (answers)A=πr²
Pressure formula - (answers)Pressure = Force/Area or P = F/A
RPM formula - (answers)60 x F /( N/2) where F(frequency is Hz) N is the number of poles
Example: what is the rotating speed of a three phase 30 HZ 6 pole motor?
60 x 30hz = 1800 1800 •/• 3 poles = 600RPM
Time constant formula in resistive capacitive circuit - (answers)T = RC where T is time in sec. R
is Resistance and C is Capacitance which is probably is in microfarads
Time constant formula in a resistive inductive circuit - (answers)T=L/R Where T is time in
seconds, L is inductance in henries and R is reaistance
formula for frequency - (answers)f=1/T where T is time(period) in seconds

Average Value Formula if given peak - (answers).636 x peak
, Peak value if given average - (answers)Peak= AVG/0.636 OR
Peak= AVG x 1.57
peak to peak value - (answers)2x peak value
Peak value when given effective or RMS - (answers)Peak= 1.414 x Effective or RMS
Peak to peak value when given RMS or effective - (answers)Peak to Peak= 2.828x RMS
Formula for unequal resistances in a parallel circuit - (answers)R= 1/
1/r1+ 1/r2.........
