3. ### How many 0.25-pF capacitors must be connected in parallel in order to store 1.2µC of charge when connected to?

Q = C*V C = Q/V = (1.2*10^-6/10) = 1.2*10^-7 Capacitors in parallel add, so if we need n capacitors C = 1.2*10^-7 = n*0.25*10^-12 n = 1.2*10^-7/(0.25*10^-12) = 4.8*10^5 = 480,000 <<<

4. ### Find the inductance if the capacitance is 6 pF.?

I will assume that when the switch is closed, a parallel circuit comprising only capacitance (C) and inductance (L) is formed. The circuit will oscillate at a natural frequency (w) given by w = sqrt(1/(L*C)). I will also assume...

6. ### What is the formula for finding power factor(pf)?

The cosine of the phase angle by which the current lags or leads the voltage is called Phase factor. If we connect a reactive element in series with one ohm resistor. The voltage across gives the current and the voltage across the reactive element gives the...

7. ### Each plate on a 3900 pF capacitor carries a charge with a magnitude of 1.6 multiplied by 10-8 C.?

Q = CV V = Q/C = (1.6e-8) / (3900 e-12) Take voltage from above and divide by distance. .

8. ### Is the Power Factor (PF) always positive?

Power factor is defined as the ratio of the real power flowing to the load to the apparent power. Since both power numbers are positive, the ratio of two positive numbers has to be positive. .

9. ### Physics: A cylindrical capacitor has a capacitance per length of 31.5 pF/m?

1. Capacitance per length = 31.5 x 10^-12 F/m C/L = 2πε / ln(b/a) b/a = exp(2πεL/C) 2. C = Q/V Q = CV Q/L = CV/L = (31.5 x 10^-12)(2.6) = 8.12 x 10^-11 C/m

10. ### At 27 centigrade the kinetic energy pf an ideal gas is E1. If the temperature is increased to 327 centigrade t?

t1 = 27ºC T1 = (273 + 27) K = 300 K t2 = 327ºC T2 = (273 + 327) K = 600 K E2/E1 = T2/T1 = 600 K / 300 K = 2 => E2 = 2E1 ===== Option 1
