Why are electrical devices rated with both a voltage and a current?
The short answer is you need power. And power is the product of voltage and current: P = V*I. As either V or I approaches zero, P approaches zero. So, you need voltage and current flow to generate the power needed to operate an electrical circuit.
Why must do the insulation testing in circuit?
Insulation resistance testing involves applying a voltage across a dielectric, and measuring the resulting current and resistance. However, in order to get a proper reading, any electrical charge still within the system needs to be taken out, so as not to mess with the readings.
What working of resistor?
The main power producers in an electrical system are the battery and alternator. The alternator puts 14 volts of alternating current into the electrical system and resistors. The resistors only allow a fraction of the AC voltage produced to reach the systems' sensitive components
Why same h parameter model is used for npn and pnp transistor?
The same h parameter model is used for npn and pnp transistors because gain is gain. It does not matter if you are using a negative or a positive system. So long as you are consistent in your calculations, you will get the correct results. In an NPN transistor operating in class A, if you increase the base current by increasing the base voltage, you will increase the collector current which decreases the collector voltage. In a PNP transistor operating in class A, if you increase the base current by decreasing the base voltage, you will still increase the collector current, which will increase the collector voltage.
What is rms unit?
The abbreviation, 'r.m.s.', represents 'root mean square', which is a way in which a.c. current (and voltage) is measured so that it may be compared with a d.c. current that does the same amount of work.
How you would use the water flow to demonstrate a low-voltage electric current?
In a water system, the "voltage" is the water pressure, the flow rate is the "current", and the pipe size is the "resistance". Low-voltage electrical current is equivalent to low-pressure water.
What is the function of shunt reator?
it is electrical device connected with high voltage current grids in order to protect the system from sudden drop or sudden change is voltage.
What is function of a divider in electrical system?
what is function of a voltage divider in electrical system
Flow of water and electric current is compared to?
Voltage is what they are compared to.
What is the electrical voltage are supplied by the power supply on your system?
The electric voltage are energy to my system.
Describe the differences between spikes and surges sags and brownouts and blackouts?
Spikes refer to sudden increases in voltage that last for a short duration, while surges are longer-lasting periods of elevated voltage. Sags are temporary drops in voltage, while brownouts are prolonged periods of reduced voltage. Blackouts are complete power outages where electricity is unavailable for an extended period of time.
What does the alternator do in a cars electrical system?
Function of Automotive AlternatorIt generates AC [alternating current] electricity which is rectified and converted to 12 volts DC [direct current] for charging the battery and operating electrical devices in the vehicle.
What is electrical checks?
The term electrical checks will differ with respect to the machine or system being referenced. Electrical checks on a car will include the DC battery Voltage, charging voltage and current and may be voltage during engine starting. On a machine it could be main voltage secondary control voltages and even specific test point voltages on a control board.
Why are electrical devices rated with both a voltage and a current?
The short answer is you need power. And power is the product of voltage and current: P = V*I. As either V or I approaches zero, P approaches zero. So, you need voltage and current flow to generate the power needed to operate an electrical circuit.
What do you call the measure of electrical pressure?
Electrical pressure is the difference in electrical potential between two points with or without current flow. Without current flow it known as an EMF (electro motive force E) with current flow it is described as a potential difference (pd V). Both are measured in volts (symbol V).
What is the purpose of voltage transformer?
A 'voltage transformer' (called a 'potential transformer' in North America) is classified as an 'instrument transformer', and is used to reduce the voltage of an electrical system to a lower, safe, level for the purposes of either operating a voltmeter or supplying a protection relay. At the same time, it electrically-isolates the meter or relay from the high-voltage system.
What is the most current version of windows client operating system?
Windows 8 is the most current windows client operating system.
