Study Notes
KCL and KVL
- KCL is based on the fact that charge accumulation is not possible at a node.
- The algebraic sum of voltages around any closed path in a network is equal to 0.
Controlled Sources
- Controlled sources are also known as dependent sources.
Nodal Analysis
- If there are n nodes in a circuit, then (n-1) node-voltage equations are required.
- If there are 10 nodes in a circuit, 9 equations are required for nodal analysis.
- A supernode is between an essential node and a reference node.
Mesh Analysis
- A loop which does not contain any other inner loop is known as a mesh.
- Super Mesh analysis can be done when there is a common current source between any two loops.
- If there are 16 branches and 5 essential nodes, 11 equations are required to describe a circuit in mesh-current method.
Semiconductor Devices
- The most widely used semiconductive material in electronic devices is silicon.
- The majority carriers in an n-type semiconductor are conduction electrons.
- Electron-hole pairs are produced by thermal energy.
- The current in a semiconductor is produced by both electrons and holes.
- The process of adding an impurity to an intrinsic semiconductor is called doping.
- A pn junction is formed by the boundary of a p-type and an n-type material.
Diodes
- When a diode is forward-biased, the current is produced by both holes and electrons.
- For a silicon diode, the value of the forward-bias voltage typically must be greater than 0.7 V.
Rectifiers
- The average value of a half-wave rectified voltage with a peak value of 200 V is 63.7 V.
- The average value of a full-wave rectified voltage with a peak value of 75 V is 53 V.
