When a fuse wire melts the electrical energy is transfered as what 2 types of energy?
kinetic and chemical energy
What are the three examples of electrical energy?
three types of electrical energy is an outlet, a lightbulb, and the sun. I know these are right because my teacher told me.
Is electric circuit also called series circuit?
The 2 simplest Electrical circuits areSeries Circuit - Same amount of current running through loads but voltage various by the resistance of the loadsParallel Circuit - Same voltage on the different loads by subject to the load resistance, the current passing through is different
How does resistance affect the current in a circuit?
Resistors are used for many things in an electronic circuit, including creating a voltage drop at some point; attenuating noise on a signal before it reaches the output stage; in combination with transistor devices, split a signal into 2 opposite phases; present a minimum load to a device to keep it working at its optimum point; to create an appropriate bias level for transistor device inputs; to control a timing circuit in conjunction with a capacitor; to create a tuned circuit in conjunction with an inductor, and/or a capacitor . . . . and the list goes on . . .
Realation of current with power and time?
There is no direct relation of electric current and power. In order to knowhow much power (or energy) the current gives up, you must know what thecurrent is flowing through.The easiest way to describe anything through which the current is flowing isto measure and state its electrical resistance.Once you know the resistance through which the current is flowing . . .Power delivered by the current = (magnitude of the current, amperes)2 x (resistance of the path, ohms)The power is delivered continuously. Its unit is watts.Each watt of power means 1 joule of energy every second.
What 2 types of currents do you commonly refer to with electricity and what do they stand for?
the two types of electrical current are AC which stands for Alternating current and DC which stands for direct current. Battery current is direct current. The electrons in alternating current flow one way and then flow in the opposite direction.
What is electric braking of DC motors?
In a dc motor, when the supply is suddenly turned off, there is a suddenly fall of speed in motor. this is reduced by means of electric effect. Hence it is called electric braking ( By @FarajAlyami electric motor braking has two types 1- electromechanical 2- electrical but electrical has some types as : 1- regenerative 2- dynamice 3- plugging ( counter - current )
What are 2 main parts of an electrical current?
battery and a switch
What causes the direction of current flow?
I assume you are referring to oceanic currents (instead of electrical current). Oceanic current is divided into 2 types: Surface Ocean Current -- affected by wind. Deep Ocean Current --cause by water density (mineral rich vs clearer water) and temperature gradient (differences in heat)
2 types of electricity?
AC and DC, alternating current and direct current.
What is the medical equipment used to emit electrical pulses to treat pain?
There are a couple types of equipment that give electrical stimulation and are used as a form of short-term pain control. Probably the two most common are: 1) TENS (Transcutaneous electrical nerve stimulation) 2) IFC (Interferential current)
The current in an electrical conductor varies inversely as the resistance of the conductor The current is 2 amperes when the resistance is 960 ohms What is the current when the resistance is?
4
How many types of losses in transformer?
Basically two types: 1. Copper losses:- when the transformer is loaded, current flows in primary and secondary winding, there is loss of electrical energy due to the resistance of the primary winding, and secondary winding and they are called variable losses. These losses depend upon the loading conditions of the transformers. Therefore, these losses are also called as variable losses. 2. Iron losses or core losses:-The losses that occur in the core are known as core losses or iron losses. Two types of iron losses are: > eddy current loss > Hysteresis loss.
What are the types of braking used in electrical motors?
Mainly 2 types of braking are used: rheostatic braking and regenerative braking
What are the basic 2 types currents?
You can have electrical currents, or currents in fluids such as water or air.
What are at least 2 types of electrical transformers in science?
A variety of electrical transformers are produced for a variety of purposes. All of the types use the same principle discovered by Michael Faraday, and employ many of the same parts. The various types include. Audio transformers, Instrument transformers, Pulse transformers, Power transformers, RF transformers. .
What is the current in a copper wire that has a resistance of 2 ohms and is connected to a 9-volt electrical source?
Current equals Voltage divided by Resistance. 9/2=4.5 amps.
