Circuits

because voltage is the 'electrical potential difference'. since a "difference" can only be evaluated between two points so is voltage :)

No, use only Distilled Water.

A voltage amplifier (high input and output impedances) with a gain

of 83.5 dB will amplify a signal of 1 millivolt to an output of 15 volts.

Circuits are not made of voltages, they are made of loops. A short circuit exists when a connection is added that is not supposed to be part of the intended circuit as designed. This added connection produces extra loops in the circuit that typically prevent current from reaching parts of the circuit where it is needed and can cause excessive current to flow in other parts of the circuit, resulting in damage to the components in the circuit.

Series circuit.

No-one created circuit symbols; they evolved over time. And, in fact, different countries use different standards for their symbols so US standard symbols, for example, are different from European standards.

It takes a battery that delivers the voltage that the bulb is designed for,

at a current of (10/bulb voltage) amperes for a reasonable length of time.

A switch is often used to activate a circuit.

Trenches are the deepest parts of the ocean. Abyssal plains are the flattest parts of the ocean, but not necessarily the deepest. For the record, Marianas Trench is the deepest trench in the world, located near the Philippines.

The current in a reading lamp would be a small part of the total current in a home. For example, a home may have 100 amp service, while a reading light may draw less than 1 amp, so about 1% of the total.

In a DC parallel circuit, equal voltage is applied to each device that is connected in parallel. For example, if three devices are connected in parallel to a 9 volt battery, each device will have 9 volts applied to it. In a DC series circuit, the sum of the voltage drops across each device connected in series equals the source voltage. So say you have three devices connected in series, and they are connected across a 9 volt battery. Each device will have less than 9 volts across it, but if you add the voltage drops across each device togther, it will equal 9 volts. Batteries in series have an additive effect to the voltage. A single AA battery has 1.5V. Two in series will have 3.0V. Batteries in parallel do not experience an additive effect to voltage. To answer this question briefly there is a big difference. The major difference is the resistance the circuit offers when the same components are wired in series or parallel. I do not know how much you want to know, but resistance of a component is measured in Ohms. An easy way to think of ohms is how much force or energy is required to move an object. The less ohms a circuit has the more it can do with the same amount of energy, which in some cases can be a bad thing. To move on, lets say you have two light bulbs, to give a cliche example, and both are 2 ohm load. Now if you wired these two light bulbs in series, connect positive of one bulb to negative of the other and then the others to a battery, the bulbs would be half as bright as one bulb to the same battery. Yet if you wired these in parallel there brightness would be the same as if one light bulb was connected to the circuit. This is because the voltage in the parallel circuit doesn't decrease when you add a light bulb, whereas on the series circuit it does decrease. Hope that helps

Those are special type transformer used for both step down and step up in a single transformer ,they are specially designed .

their wire thickness in both winding is thicker than ordinary step up or down transformer.and they are costly too.

Because , ic can provide :-

1. very high gain

2. compact & less bulky circuit

The flow of electric current is controlled by the voltage applied to a circuit. Voltage creates an electric field that pushes charged particles (electrons) through a conductor, allowing current to flow. The resistance in the circuit also affects the flow of current, as it determines how much opposition the current encounters.

They are the negative and positive terminals. Higher potential andl ower potential terminals

It is a type of resistor called a potentiometer, which is a resistor with a movable center tap. The full volume signal is applied across the full resistor and the variable volume signal is taken off the movable center tap.

your mom ok

The maximum current that a cell can deliver flows when the resistance between

the terminals of the cell is zero. This situation occurs when the terminals are

connected by a conductor with very low resistance, such as a thick wire or a

wrench. But not for long.

-- A stack of several cells connected in series presents several times the voltage

of a single cell.

-- The current depends on the 'load' connected between the battery's terminals.

But since the current through any load is directly proportional to the voltage across

it, several cells in series ... with their increased voltage ... will produce several times

as much current as the same load would draw from a single cell.

Since 1998, the standard mains supply throughout Indonesia is 230 volts, 50 Hz.

Domestic: 240 V AC, 50 Hz

Industrial: 400 V AC, 50 Hz

Plugs used for 240 V: BS-546 and BS-1363

the current is raped from it's present to some a new value .

Expanding or collapsing magnetic field units a cross coil and induces a voltage that opposite di/dt

Connecting batteries in series increases available voltage. Connecting them in parallel increases available current. Ohm's law states that when resistance is constant (and a light bulb is a constant resistance, to a point), the current flowing through will be directly proportional to the voltage. And when the voltage doesn't change, the only way to change the flowing current is to lower the resistance - as in, put in a smaller light bulb.
