If you cause a small electric current to flow through the coil, the coil be- comes a magnet and the magnetic forces— between the wire coil magnet and the horseshoe magnet — cause the coil electricitj turn until the magnetic turning force is balanced by the force due to tension in the spring. The Parts of an Elementary Generator. Unaware I would soon be back in school, I picked up a copy and dug in. You will use the dry cell in many different sizes, shapes and weights — from the cell used in a pencil-size flashlight to the extra large dry cell used in emergency lanterns.

Review of How Electricity Is Produced The Basic Electronics portion of this course will be available as a separate series of volumes. Fixed wire-wound resistors are also used which have coating other than vitreous enamel.
This outward curve, or stretching effect, is caused by the repulsion of each magnetic line from its neighbor.
Most storage batteries consist of three lead-acid cells in a common case permanently connected in series.

Since the meter scale permits reading to two places directly, the interpolation is the third figure of the reading. Before going on to learn about the other basic sources of electricity, you valkemburgh review those facts which you have already learned.
If you were to look inside a dry cell, you would find that it consists of a zinc case used as the negative plate, a carbon rod suspended in the center of the case for the positive plate, and a electriciyy of ammonium chloride in paste form for the electrolyte.
Movement is necessary because the magnetic field around a magnet pro- duces an electric current in a wire only when the magnetic field is moved across the wire. Across these leads, he connects each of the voltmeters in turn.
Voltage exists, for example, between two unequal positive charges or between two unequal negative charges. To indicate the amount of current flow a lightweight pointer is attached to the coil and turns with the coil. In order to generate large amounts of electricity a much stronger magnetic field must be used.

You also see that for voltages of less than 6 volts the lamp is dim — indicating that the voltage is too valkenubrgh for proper operation. To provide continuous motion, the wire or the magnet would need to move back and forth continuously.
The unit of current flow is the ampere. The two outside layers act like electrodes. When the potential difference between two charges is between one -thousandth of a volt arid one volt, the unit of measure is the millivolt; when it is between one-millionth volt and one- thousandth volt, the unit is the microvolt.
Carbon resistors are of two types, radial and axial, which differ only in the way in which the wire leads are connected to the body of the resistor.
The voltage between the terminals then would fall to zero volts and current flow would no longer take place. The action of the magnetic poles in attracting and repelling each other is due to the magnetic field around the magnet. You have also seen eleftricity static charges can be transferred by contact or in- duction, and you have learned about some of the useful applications of static electricity.

Jack rated it it was ok Feb 21, Power Rating of Equipment In order for current eleectricity flow, a continuous path must be provided between the two terminals of a source of electric charges. Normally, panel-mounting type me- ters are calibrated and adjusted for use in a vertical position.
eletricity Meter scale ranges for milliammeters and microammeters, like ammeters, are in multiples of 5 or 10 since these multiples are easily changed to oth- er units. There are many types of primary cells used in laboratories and for special ap- plications, but the one which you have used and will be using most often is the dry cell. Stephen rated it really liked it Dec 22, The carbon coating is covered with baked enamel, for protection and to conduct heat away from the carbon film so that it does not overheat and burn out.

For example, in volume measure one-half gallon equals two quarts, and four pints also equals two quarts.
