Ohmic conductor & Non-Ohmic conductor – differences

Differences between Ohmic conductors and non-ohmic conductors with respect to Ohm’s law, V-I graph, resistance constancy or not – are listed in this post. Difference between Ohmic & Non-Ohmic conductor Ohmic conductors are conductors that obey Ohm’s Law. The V-I curves of these conductors are linear. Resistance is independent of Voltage and Current for these […]

RRC and RAR in 8085

In this post, we will see with examples how RRC and RAR instructions in 8085 work and how they differ in their operations. Instruction RRC and RAR are basically two logical instructions available in instruction sets of 8085, to rotate the bits of the accumulator one position to the right. Define RRC and RAR instructions […]

AND Gate – definition, symbol, & Truth Table

An AND gate is a logic circuit having two or more inputs and one output. The output of an AND gate is HIGH only when all of its inputs are in the HIGH state. In all other cases, the output is LOW. When interpreted for a positive logic system, this means that the output of […]

Calculating the percentage of an element in a compound

Here, with an example, we will see how to calculate the percentage of an element in a compound. Relative atomic masses can also be used to calculate the percentage of different elements in a compound. For example:carbon dioxide (CO2) contains 12 g of carbon and 2 × 16 g of oxygen in 44 g of […]

Properties of P-type and N-type material & their differences

let us go through the properties of P-type and N-type semiconductors. Then we will compare P-type and N-type semiconductors, as well. P-type and N-type material In Figure 1, the left side material is a P-type semiconductor having negative acceptor ions and positively charged holes. The right side material is an N-type semiconductor having positive donor […]

Commonly used semiconductors: Germanium & Silicon

There are many semiconductors available, but very few of them have practical applications in electronics. The two commonly used materials are Germanium (Ge) and Silicon(Si). In Ge and Si, the energy required to break the covalent bond (energy required to release an electron) is very small. For Ge, it is 0.7 eV and for Si, […]

Thermal Conductivity – Numerical problems

Converting L atm to Joule | Litre Atm to Joule

Here in this post, we will convert L atm to Joule. L atm is also known as Litre Atmosphere. L atm to Joule L atm is the product of 2 units and these 2 units are Litre (unit of volume) and Atmospheric pressure (or atmosphere which is a unit of pressure). L atm, hence, is […]

The effect of air resistance on projectile motion

In this post, we will find the effect of air resistance on projectile motion. We have seen that in the absence of air resistance, the trajectory or path followed by a projectile is a parabola and that the path depends only on the initial speed and angle of projection. But in the real world, all […]
