Report on the impacts of lock-down on company's business
Explanation:
As a result of detailed analysis and market research, the following impacts have been identified due to the lock-down on the company's business
- Sales have been reduced drastically due to the lower interest of people in dine-in or takeaways
- Loss due to the wastage of stored goods
- However, policy change of delivering to homes made a positive impact but it had to be done on discount rates to increase public interest which again did not produce much profit
- Additional charges for delivery also caused the loss

Conductor resistance is a property of a conductor at a specific temperature, and it is defined as the amount of opposition there is to the flow of electric current through a conducting medium.[2] The resistance of a conductor depends on the cross sectional area of the conductor, the length of the conductor, and its resistivity. It is important to note that electrical conductivity and resistivity are inversely proportional, meaning that the more conductive something is the less resistive it is.
The resistance of a conductor can be calculated at a temperature of 20°C using:[3]
R=ρLA R=ρLA
where:
RR is the resistance, in ohms (Ω)
ρρ is the resistivity of the material in ohm meters (Ωm)
LL is the length of the conductor in meters (m)
AA is the cross-sectional area of the conductor in meters squared (m2)
This formula tells us that the resistance of the conductor is directly proportional to ρρ and LL, and inversely proportional to AA. Since the resistance of some conductor, such as a piece of wire, depends on collisions within the wire itself, the resistance depends on temperature. With increasing temperature, the resistance of the wire increases as collisions within the wire increase and "slow" the flow of current. The amount of change is determined by the temperature coefficient.[4] A positive temperature coefficient results in resistance increasing with temperature whereas a negative temperature coefficient results in a decreasing resistance with an increasing temperature. Since conductors typically display an increased resistivity with temperature increase, they have a positive temperature coefficient. The most common types of resistors are variable resistors and fixed resistors.
