Relative Permeability of Paramagnetic Substances
- Relative permeability of paramagnetic substances is slightly greater than 1.
Window Comparator Op-amps
- A window comparator requires 3 op-amps.
Resistor Noise Classification
- Resistor noise is classified as white noise.
Battery Life Calculation
- A 100 Ah, 24V battery with a 300W electronic equipment load and a 50W light load will last approximately 6.86 hours.
Oscillator Principle
- A Klystron oscillator operates on the principle of velocity modulation and changing the speed of electrons passing through the tube.
Single Decimal Digit Count
- The highest count possible with a single decimal digit is 9.
Chemical to Electrical Energy Conversion
- A battery converts chemical energy to electrical energy.
Materials with Free Electrons
- Conductors have more free electrons than other materials.
Storage Devices

Ohm's Law Applicability
- Ohm's law is applicable to linear circuits.
Dynamic Memory Information Storage
- Dynamic memory stores information as long as power is applied and the memory is refreshed.
Signal Generator use in Receiver Testing
- Signal generators are used in receiver testing to generate either modulated or unmodulated signals. Receiver alignment and voltage/current graphs display are also used.
Non-linear Resistor
- A varistor is a non-linear resistor whose resistance changes with voltage.
Parallel Cells
- Parallel cells have the same voltage as one cell but have different current capacity.
Ferromagnetic and Paramagnetic Materials
- Materials with permeabilities slightly less than free space are called paramagnetic.
Logic Circuit with Multiple Inputs
