NETWORK ELEMENTS
We can classify network elements into 4 types:
1. Active / Passive Elements
2. Bilateral / Unilateral Elements
3. Linear / Non-Linear Elements
4. Lumped / Distributed Elements
Read MoreFAQs on PPT: Introduction of Electric Circuit
| 1. What exactly is an electric circuit and how does current flow through it? |  |
Ans. An electric circuit is a closed loop path through which electric current flows from a power source (like a battery) through conductors and components back to the source. Current flows when there's a complete path and a potential difference; breaking this path stops current flow instantly. Understanding circuit fundamentals helps students grasp how electrical devices actually operate.
| 2. What's the difference between open circuit and closed circuit in basic electrical technology? | |
Ans. A closed circuit has a complete conducting path allowing current to flow freely, while an open circuit has a break in the path, preventing current flow entirely. Think of a light switch-closed means "on," open means "off." This distinction is fundamental to circuit analysis and appears frequently in CBSE exams.
| 3. Why do we need both voltage and current to understand how circuits work? | |
Ans. Voltage (electrical pressure) drives current (flow of charge) through a circuit; neither alone is sufficient. Voltage pushes electrons, but current measures how many electrons actually move. Together, they determine power consumption and help predict circuit behaviour. Students often confuse these two, making this a critical conceptual foundation.
| 4. How do I identify series and parallel circuits just by looking at a circuit diagram? | |
Ans. In series circuits, components connect end-to-end in a single path, sharing the same current. In parallel circuits, components branch off with multiple paths, each receiving full voltage but splitting current. Series arrangements use less wire but fail completely if one component breaks; parallel arrangements stay functional if one path fails-a key practical difference.
| 5. What are the basic symbols and components I need to recognise in any electric circuit diagram? | |
Ans. Standard symbols include cells (battery), resistors, switches, wires, and bulbs. Cells provide energy, switches control flow, resistors limit current, and wires conduct electricity. Learning these symbols is essential for reading circuit diagrams. Refer to mind maps and flashcards on EduRev to memorise these instantly before your electrical technology assessments.
