Self-Inductance of Circular Ring of Round Wire at Radio Frequencies, for Nonmagnetic Materials

L = (a/100) X [7.353 log 10(16a/d) — 6.386]

Where,

L = self-inductance in microhenrys,
a = mean radius of ring in inches,
d = diameter of wire in inches,
aid> 2.5.

* Many equations for computing capacitance, inductance, and mutual inductance will be found in Bureau of Standards Circular No. C74, obtainable from the Superintendent of Documents, Government Printing Office, Washington, D.C. 20402.

Capacitance

For Parallel-Plate Capacitor:

where,

C 0.0885€r[(N — l)Ajit
=
0.2256r[(N — 1)A”/t”]

A = area of one side of one plate in square centimeters,
A” = area in square inches,
N = number of plates,
= thickness of dielectric in centimeters,
= thickness in inches,
= dielectric constant relative to air.

This equation neglects “fringing” at the edges of the plates.

For Coaxial Cylindrical Capacitor (Fig. 8):

C = 2TErE/[log(b/a)]

= {(5 x 106e)/[c2log(b/a)]}

where,

C = capacitance per unit axial length in farads/meter,
c velocity of light in vacuo, meters per second
= 2.998 X 108,
= dielectric constant relative to air,
= permittivity of free space in farads/meter
= 8.85 x 10-12

Alternative forms of the equation are:

When 1.0 < (b/a) < 1.4, then with accuracy of 1 percent or better, the capacitance in picofarads/foot is:

(b/a) + 1 C = 8.5OEr
(b/a)

T-ir or V-A Transformation

The two networks (Fig. 9) are equivalent, as far as conditions at the terminals are concerned, provided the listed equations are satisfied (either the impedance equations or the admittance equations may be used)
Y1 = 1/Z1 Y = 1/Zr, etc.

Simple Relay Circuit

The following schematic illustrates the Simple Relay Circuit Diagram.

Simple Doorbell Wiring Diagram

The following link provides you detailed information on how to design a simple doorbell for home application. The doorbell wiring diagram consists of: AC power input, doorbell transformer, bypass switch, solid state relay, doorbell button, ATtiny12 timer, capacitor, and a 5 watt power supply. The ATtiny11/12 is a low-power CMOS 8-bit microcontroller designed and produced by ATMEL semiconductor.

Simple Op Amp Radio Circuit Diagram

The following schematic shows the Simple Op-Amp Radio Circuit Diagram taken from bowdenshobbycircuits.info. This Simple Op-Amp Radio is basically a crystal radio with an audio amplifier. It uses germanium diode (1N34A type). The circuit draws about 10 mA from a 9 volt source.

Simple Car Circuit Breaker Schematic Diagram

Circuit breaker is an electronic devices which function is to protect an electrical circuit from hazard/damage due to overload or short circuit. This car circuit breaker circuit presented here will automatically cut off the power, thus avoiding any possible electrical hazards.
