What is an oscilliscope used for?
An Oscilliscope is used for measuring signal voltages and the wave shape in an electrical signal. One can find detailed information about them on Wikipedia.
What is an electrical battery?
It is a storage device for D.C. voltages.
Why a fuse of high voltage is used for electrical appliances of less voltages in comparison to fuse?
for those appliances do not break immediately...........
Are fuse used to detect electrical energy?
Fuses are overcurrent protection devices. If voltages get extreme they blow to save other components. So yes in a way they detect electrical energy.
What is the best private university in Bangladesh for electrical and electronic engineering?
Bangladesh University of Science and Technology
What is a electrical contactor for?
An electrical contractor does the wiring for homes and businesses. They install the wiring and electrical components needed to run electricity. The question asks about a contactor, not a contractor. A contactor is a type of heavy duty electrical relay for using smaller voltages to control much larger voltages.
What are some cautions to electrical energy?
It's dangerous at high voltages.
Why are a range of voltages used?
Several reasons for different voltages. At the heart of it is that to deliver the same power, voltage and current are inversely related. The other aspect is safety. So for the grid, high voltages are used to maximize power transmission within the current limits of the cables. In industrial environments, equipment may require a lot of power - that requires high voltages as well Domestic requirements are not so power-hungry so 120 or 240 volts are adequate, and are also safer (well... less dangerous) than higher voltages.
Is kirchofs law is concerrned with junction voltages?
Yes, Kirchhoff's laws are concerned with voltages at junctions in electrical circuits. Specifically, Kirchhoff's Voltage Law (KVL) states that the sum of the electrical potential differences (voltages) around any closed circuit loop must equal zero. This implies that at any junction, the voltages across the components connected to that junction must balance out. Thus, KVL is essential for analyzing circuits involving junctions and their voltages.
What is the starting Salary of an Electrical Engineer in Bangladesh?
baaal 100 tk
What voltages should never be measured directly with a VOM?
A VOM 'Voltage Meter' measures from a electrical outlet. Any voltage over a 1000 should never be measured directly with it.
What is the advantage of using network reduction in electrical circuits?
It makes the calculation of currents and voltages easier.
