Alternating current bridges….it’s applications and various perspectives revealed….. ALTERNATING CURRENT BRIDGES:- INTRODUCTION:- A bridge circuit is a type of electrical circuit in which two circuit branches (usually in parallel with each other) are "bridged" by a third branch connected between the first two branches at some intermediate point along them. The bridge was originally developed for laboratory measurement purposes and one of the intermediate bridging points is often adjustable when

are non-linear consumers. Non-linear consumers produce harmonic currents which flow through the electric power network. They cancel out in generators and other consumers. The results of those currents are harmonic voltages. Both harmonic voltages and canceling out harmonic currents affect performance of other consumers connected to the electric power network. Because most electrical systems were designed for linear voltage and current waveforms (i.e. nearly sinusoidal)‚ excessive nonlinear loads can

Record the initial current reading shown on the ammeter. As the current flows in the magnet wire‚ the temperature of the wire will be increasing. Measure the temperature using the infrared thermometer. Record the ammeter reading as the temperature increases 10°C before disconnecting the wire from

nature of the material. In a gas discharge‚ such as a fluorescent lamp‚ current causes resistance to decrease. This is because as more electrons and ions flow through a particular area‚ they bump into more atoms‚ which frees up electrons‚ creating more charged particles. In this way‚ current will climb on its own in a gas discharge‚ as long as there is adequate voltage (and household AC current has a lot of voltage). If the current in a fluorescent light isn’t controlled‚ it can blow out the various

Definition of ’Current Account Deficit’ Occurs when a country’s total imports of goods‚ services and transfers are greater than the country’s total export of goods‚ services and transfers. This situation makes a country a net debtor to the rest of the world. ’Current Account Deficit’ A substantial current account deficit is not necessarily a bad thing for certain countries.

If short lengths of wire are used with relatively high currents and voltages‚ then significant electrical heating may also occur. Students should be encouraged to adjust the voltage to keep currents small with every set of readings. At each stage they can connect the circuit‚ take readings quickly and then

instruments‚ simple circuit elements and we studied Ohm’s law. Theory In electrical circuits‚ we are concerned with the flow of electrical current around closed loops made up of wires‚ meters and other components. For this unit we measured and calculated electrical quantities such as direct current‚ voltage and resistance. Current Electrical current is the rate at which electrical charge flows around a circuit. It is measured in units of amperes (A) by ammeters. Potential Difference (voltage)

their travels. We define electrical resistance as the ratio of voltage to current. The equation we use to find the resistance from the current and voltage is: Resistance (R) = Voltage (V) ÷ Current (I) Put more simply‚ it is the number of volts difference across the object when one amp of current flows. You should recall that voltage is the number of joules of energy transferred by one coulomb of charge‚ and that current is the number of coulombs of charge passing a place each second. What the
