One of the basic form of energy and can be generated in many ways

Other name for batteries and cells

Converts chemical energy into electricity

Coverts solar energy to electricity

Needs battery as energy storage to operate during night time

When the coil is perpendicular to the field, the induced emf is?

When the coil is parallel to the field, the induced emf is?

As the coil turns through the perpendicular, the direction of the current is reserved.

True

False

The higher the frequency of revolution, the lesser the rate of change of flux, and the higher the induced emf.

True

False

Primary difference between a simple AC and simple DC generator

Commutator used in DC generator

Commutator used in AC generator

Consist of coils of conductors within the generator that receive a voltage from a source and produce a magnetic flux.

Consist of many coils of wire that are large enough to carry the full-load current of the generator.

Component that is used to drive the AC generator

The rotating component of the generator

The rotor will be the armature if the voltage output is not generated there

True

False

The rotor will be the armature if the field excitation is applied there

True

False

Is the part that is stationary

Are electrical connections that are used to transfer power to and form the rotor of AC generator

Consist of a circular conducting material that is connected to the rotor windings and insulated from the shaft

In a DC generator, this was used to provide an output whose current always flowed in the positive direction

This oscillation of the voltage and current takes the shape of a cosine wave

True

False

Is the time rate of flow of electrical charge though a conductor or circuit element

When a current is constant with time

When a current varies with time

Is the energy transferred per unit charge that flows through the element

If positive charge moves from the positive polarity through the element toward the negative polarity, the element supplies energy that appears as heat or some other form.

True

False

If positive charge moves from negative polarity toward the positive polarity, the element supplies energy

True

False

The product of current and the voltage

Consists of various types of circuit elements connected in closed path by conductors.

When elements are connected end to end

If both ends of one element are connected directly (e.g. conductor) to corresponding ends of the other

One important factor to consider in planning a Farm/residential electrical system

Are the unit describing the amount of light (energy) as seen by the human eye that is given off by the light bulb

Defined as being equivalent to one lumen spread over an area of one square meter.

Means glowing due to heat.

An efficiency of two to three times as many lumens per watt as an incandescent.

Spiraled light bulbs are far more efficient than the standard incandescent bulb

Work by running electricity through gas inside the coils, exciting that gas, and producing light.

Is one of today's most energy-efficient and rapidly-developing lighting technologies.

A bulb with halogen gas

Very bright and they produce very white light and have good color rendition

The most commonly used street light throughout the world

Works similarly to HPS but produces almost exclusively yellow light.

Energy savings are significant, but produces a lot of blue light which can have a negative effects on human health and wildlife

Have only been on the market for the past few years. They use very little energy and have good color rendition

Rather than emitting all the colors of the rainbow and a lot of blue light, they emit mostly in the yellow.
