How do you derive relation between focal length and radius of curvature of concave mirror?
Consider a ray of light AB, parallel to the principal axis, incident on a spherical mirror at point B. The normal to the surface at point B is CB and CP = CB = R, is the radius of curvature. The ray AB, after reflection from mirror will pass through F (concave mirror) or will appear to diverge from F (convex mirror) and obeys law of reflection, i.e., i = r. From the geometry of the figure, If the aperture of the mirror is small, B lies close to P, BF = PF or FC = FP = PF or PC = PF + FC = PF + PF or R = 2 PF = 2f or F=R/2 or 2F=R Hope this helps............

What is meant by transistion and space charge capacitance of a diode?
Diffusion capacitance is the capacitance due to transport of charge carriers between two terminals of a device. - Amog This diffusion capacitance is due to depletion capacitance which is a function of forward bias applied to emitter junction of a transistor and due to diffusion capacitance which a function of transconductance of the transistor. Its value is 100 pF. Tirupanyam B.V
How do you recognise the values and identify polarity and any other orientation requirements for all electronic components being used in the assemblies?
If there’s enough room on the capacitor, most manufacturers of electronics components print the capacitance directly on the capacitor along with other information such as the working voltage and perhaps the tolerance. However, small capacitors don’t have enough room for all that. Many capacitor manufacturers use a shorthand notation to indicate capacitance on small caps.If you have a capacitor that has nothing other than a three-digit number printed on it, the third digit represents the number of zeros to add to the end of the first two digits. The resulting number is the capacitance in pF. For example, 101 represents 100 pF: the digits 10 followed by one additional zero.If there are only two digits listed, the number is simply the capacitance in pF. Thus, the digits 22 indicate a 22 pF capacitor.This shows how some common capacitor values are represented using this notation:Marking Capacitance (pF) Capacitance (ìF)101 100 pF 0.0001 ìF221 220 pF 0.00022 ìF471 470 pF 0.00047 ìF102 1,000 pF 0.001 ìF222 2,200 pF 0.0022 ìF472 4,700 pF 0.0047 ìF103 10,000 pF 0.01 ìF223 22,000 pF 0.022 ìF473 47,000 pF 0.047 ìF104 100,000 pF 0.1 ìF224 220,000 pF 0.22 ìF474 470,000 pF 0.47 ìF105 1,000,000 pF 1 ìF225 2,200,000 pF 2.2 ìF475 4,700,000 pF 4.7 ìFYou may also see a letter printed on the capacitor to indicate the tolerance. You can interpret the tolerance letter as follows:Letter ToleranceA ±0.05 pFB ±0.1 pFC ±0.25 pFD ±0.5 pFE ±0.5%F ±1%G ±2%H ±3%J ±5 %K ±10%L ±15%M ±20%N ±30%P –0%, + 100%S –20%, + 50%W –0%, + 200%X –20%, + 40%Z –20%, + 80%Notice that the tolerances for codes P through Z are a little odd. For codes P and W, the manufacturer promises that the capacitance will be no less than the stated value but may be as much as 100% or 200% over the stated value.For codes S, X, and Z, the actual capacitance may be as much as 20% below the stated value or as much as 50%, 40%, or 80% over the stated value. For example, if the marking is 101P, the actual capacitance is no less than 100 pF but may be as much as 200 pF. If the marking is 101Z, the capacitance is between 80 pF and 180 pF.

A circuit contains a 10 pF capacitor and a 50 pF capacitor connected in parallel.What is the total capacitance of this circuit?
When capacitors are connected in parallel, the total capacitance in the circuit in which they are connected is the sum of both capacitances. Capacitors in parallel add like resistors in series, while capacitors in series add like resistors in parallel.

What is the Relationship between power factor and current?
When voltage and current waveforms are out of synch the power factor is reduced. In a pure resistance load the PF is 1. When inductance and capacitance is involved the PF is from 0 to 1.
What is the unit of measure for capacitance?
The Farad is used to measure capacitance. Most small electronic capacitors are in microFarads(uF) or picoFarads (pF). The unit is name after Michael Faraday, the English chemist and physicist.

How you can calculate capacitor bank value to correct pf to 0.9 lag?
Power factor (PF) is calculated and PF=cos(phi) where phi is the phase angle of the current running through a load. To find the phase angle of the current, one must know the voltage drop across the load and the total impedance (capacitance + resistance) of the load and then use Ohm's Law to find the current. The total impedance of a capacitor is 1/(j*w*C) where j = sqrt(-1), w = 2*pi*f (f = frequency), and C is the capacitance. To find the correct value of capacitance for a PF of 0.9 lag, you need to know the total impedance of the load which includes the value of the resistance and the configuration of the load (parallel, series, or some combination).
