Components of GIS:
1. Software: GIS software gives the functions and tools required to store, analyze, and show geographical information. The key software elements are:
2. Data is possibly the most significant component of a GIS. Geographical data and related tabular data could be collected in-house or purchased from a commercial data provider.
3. People: GIS technology is limited without the people who manage the system and develop plans for applying it to real-world problems. It users range from technical specialists who design and managed the system to those who use it to help them perform their everyday work
By means of nodal analysis, find the current delivered by the 10-V source and the voltage across the 10- resistance in the circuit shown in figure.
Q. Explain the working principle of a TRIAC. "Triac" is an abbreviation for three terminal ac switch. 'Tri'-indicates that the device has three terminals and 'ac' indicates tha
