Which metal is a poor conductor of electricity?
Which metal is a poor conductor of electricity? Bismuth and tungsten are poor conductors of electricity. Can diamonds stop a bullet? Pound for pound, diamonds are not very good at stopping bullets.

What are the disadvantages of using aluminum wire?
What are the disadvantages of using aluminum wire? The disadvantage of aluminum wiring is that it must be installed correctly to avoid the risk of house fires. When a current runs through aluminum wiring it causes the metal to expand. This creates a cycle of expanding and contracting called “cold creep.” In time, this can […]
What is the error in saying the source of electrons?
Why diesel engines are called CI engines?
Why diesel engines are called CI engines? Diesel engines are sometimes called compression-ignition engines because initiation of combustion relies on air heated by compression rather than on an electric spark. In a diesel engine, fuel is introduced as the piston approaches the top dead centre of its stroke. What is the difference between SI & […]
What do you mean by cost efficiency?
What do you mean by cost efficiency? As explained in the example above, cost-efficiency is a type of business efficiency strategy. Simply put, it is the act of saving money by making a product or performing an activity in a better way. Businesses measure cost-efficiency by monitoring the ratio of the output produced to the […]
