M stands for mix design in M-20 concrete, indicating the compressive strength of the concrete mix.
M-20 concrete is a mix design where 'M' represents the compressive strength of the concrete after 28 days of curing.
The number '20' in M-20 concrete indicates the characteristic compressive strength of concrete in N/mm^2.
Different grades of concrete have different compressive strength requirements, with M-20 being a common
IS 10262 is required for mix design in civil engineering.
IS 10262 is the code for concrete mix design in India.
It provides guidelines for proportioning of concrete ingredients based on strength and durability requirements.
The code covers various aspects such as water-cement ratio, workability, and compressive strength.
Mix design is crucial for ensuring the desired properties and performance of concrete.

IEC codes and standards are international standards for electrical engineering.
IEC stands for International Electrotechnical Commission
IEC codes and standards ensure safety, reliability, and compatibility of electrical systems and equipment
Examples of IEC standards include IEC 60601 for medical electrical equipment and IEC 61850 for communication networks and systems in substations
Voltage drop is the reduction in voltage that occurs as electricity flows through a circuit due to resistance.
Calculate the total resistance of the circuit
Determine the current flowing through the circuit
Multiply the current by the total resistance to get the voltage drop
Use Ohm's Law (V=IR) to calculate voltage drop across individual components
Consider using voltage drop calculators or tables for more complex circuits
