2026 QUESTIONS WITH SOLUTIONS
GRADED A+

●● 1" is equal to ______mm. Answer: 25.4 mm


●● Circumference Formula. Answer: C = 2πr


●● Area of a circle. Answer: A=πr²


●● Pressure formula. Answer: Pressure = Force/Area or P = F/A


●● RPM formula. Answer: 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. Answer: 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. Answer:
T=L/R Where T is time in seconds, L is inductance in henries and R is
reaistance


●● formula for frequency. Answer: f=1/T where T is time(period) in
seconds


●● Effective Value (RMS) formula if given peak. Answer: 0.707 x peak
value


●● Average Value Formula if given peak. Answer: .636 x peak


●● Peak value if given average. Answer: Peak= AVG/0.636 OR
Peak= AVG x 1.57


●● peak to peak value. Answer: 2x peak value


●● Peak value when given effective or RMS. Answer: Peak= 1.414 x
Effective or RMS


●● Peak to peak value when given RMS or effective. Answer: Peak to
Peak= 2.828x RMS


●● Formula for unequal resistances in a parallel circuit. Answer: R= 1/
