Maxwells inductance bridge solution and equation evaluation

     The bridge circuit is used for medium inductance and can be arranged to yield results of considerable precision. As shown in figure 1, in the two arms, there are two pure resistances so that for balance relations, the phase balance depends on the remaining two arms. If a coil of unknown impedance Z₁ is placed in one arm, then its positive phase angle ɸ₁ can be compensated for in either of the following two ways:

1. A known impedance with an equal positive phase angle may be used in either of the adjacent arms (so that ɸ₁ = ɸ₂ or ɸ₁ = ɸ₄), remaining two arms have zero phase angles (being pure resistances). Such a network is known as Maxwell’s a.c. bridge or L₁/L₄ bridge.
2. Or an impedance with an equal negative phase angle (i.e. capacitance) may be used in opposite arm (so that ɸ₁ + ɸ₃ = 0). Such a network is known as Maxwell-Wien bridge or Maxwell’s L/C bridge.

Hence, we conclude that inductive impedance may be measured in terms of another inductive impedance (of equal time constant) in either adjacent arm (Maxwell Bridge) or the unknown inductive impedance may be measured in terms of a combination of resistance and capacitance (of equal time constant) in the opposite arm (Maxwell-Wien bridge). It is important, however, that in each case the time constants of the two impedance must be matched.As shown in figure 1.

Z₁ = R₁ + jX₁ = R₁ + jωL₁…….unknown;

Z₄ = R₄ + jX₄ = R₄ + jωL₄….…known;

R₂,R₄ = known pure resistances; D = detector

The inductance L₄ is a variable self-inductance of constant resistance, its inductance being of the same order as L₁. The bridge is balanced by varying L₄ and one of the resistance R₂ or R₃. Alternatively, R₂ and R₃ can be kept constant and the resistance of one of the other two arms can be varied by connecting an additional resistance in that arm.
The balance condition is that Z₁Z₃ = Z₂Z₄

(R₁ + jωL₁)R₃ = (R₄ + jωL₄)R₂

Equation the real and imaginary parts on both sides, we have

Z₁ = R₁ + jX₁ = R₁ + jωL₁…….unknown;

Z₄ = R₄ + jX₄ = R₄ + jωL₄….…known;

R₂,R₄ = known pure resistances; D = detector

The inductance L₄ is a variable self-inductance of constant resistance, its inductance being of the same order as L₁. The bridge is balanced by varying L₄ and one of the resistance R₂ or R₃. Alternatively, R₂ and R₃ can be kept constant and the resistance of one of the other two arms can be varied by connecting an additional resistance in that arm.
The balance condition is that Z₁Z₃ = Z₂Z₄

(R₁ + jωL₁)R₃ = (R₄ + jωL₄)R₂

Wheatstone bridge ac circuit explanation and equation solution

     Resistance can be measured by direct-current Wheatstone bridge having resistance in each arm. Inductance and capacitance can also be measured by a similar four-arm bridge, but instead or using a source of direct current alternating current is employed and galvanometer is replaced by a vibrating galvanometer (for commercial frequencies or by telephone detector if frequencies are higher 500 to 2000 Hz.). The general form of an ac bridge arms Z₁, Z₂, Z₃ and Z₄ are indicated as unspecified impedances and the detector is represented by headphones. During the balance condition in this ac bridge is reached when the detector response is zero or indicated a null. The condition for bridge balance requires the potential difference from A to C to zero.

At balance con condition,

E_BA = E_BC or I₁Z₁ = I₂Z₂ ———————–(i)

I₁ = E/(Z₁ + Z₄), I₂ = E/(Z₂ + Z₃)—————–(ii)

From equation (i) and (ii)

(Z₁E)/(Z₁+Z₄) = (Z₂E)/(Z₂+Z₃)

Or, Z₁Z₃ = Z₂Z₄——————————-(iii)

      Equation (iii) states that the product of impedances of one pair of opposite arms must equal the product of impedance of the other pair of opposite arms.
If the impedance are expressed in complex notation, i.e

.                                                              Z = Z<θ

Or, (Z₁< θ₁)(Z₃< θ₁) = (Z₂< θ₂)(Z₄< θ₄)

Z₁Z₃< θ₁+ θ₃ = Z₂Z₄< θ₂ + θ₄ ——————————-(iv)

From equation (iv), we can also write,

Z1Z3 = Z2Z4

The products of the magnitudes of the opposite arms must be equal.

<θ₁ + <θ₃ = <θ₂ + <θ₄

The sum of the phase angles of the opposite arms must be equal.

Tips to improve or boost your android phone and smart phone battery life

 Today's Android phones pack big bright screens and high-end features that suck plenty of power; here's how to squeeze the most juice out of your battery. 

Top-notch Android smartphones like the Samsung Galaxy  at Amazon and HTC One (M8) are powerful, but unfortunately, they don't have endless battery life. In fact, many Android phone users would be happy to make it through a single day, hoping that a nightly recharge is sufficient.

     Sadly, it sometimes isn't. A number of factors have conspired to reduce gadget endurance over the past several years. Thinner designs with less room for batteries, larger and brighter screens, faster quad-core processors, more software that runs in the background, and power-hungry GPS radios all share responsibility. The move from 3G to 4G networks a few years ago—particularly of the LTE variety—has also taken its toll.

   But there's much more to poor battery life results than that. Fortunately, there's plenty you can do to stem the flow of juice from your Android device. To write this article, I used a Google Nexus 5, as it's running the latest version of Android 4.4 KitKat with no extra interface enhancements, but these tips should apply across just about any Android phone. Try these tips to extend your handset's battery life:

   See what's sucking the most juice. Navigate to Settings > Battery to see an organized breakdown of what's consuming your phone's battery. Applications and features will display in a descending list of battery hogs. If you see an application you barely use or a feature you never use, you'll want to uninstall the app or turn off the feature.
