The current flowing through a conductor connected to a 110-volt source can be calculated using Ohm’s law. Ohm’s law states that current (I) equals voltage (V) divided by resistance (R). Here, with a resistance of 440 ohms and a voltage ...
The resistance of an ideal voltmeter is infinite. An ideal voltmeter does not draw any current from the circuit it is measuring; therefore, it has infinite resistance. This ensures that it does not affect the circuit being measured and accurately ...
Metals are good conductors of electricity because they have free electrons. These free electrons allow electrical charge to move easily through the metal, enabling efficient conductivity. This property is a key characteristic of metals and is the primary reason they ...
When an ebonite rod is rubbed with the skin of a cat, the ebonite rod becomes negatively charged. This happens because the rod gains electrons from the cat’s skin, resulting in an excess of electrons on the rod, which gives ...
Lambert’s law relates to the absorption of light by a material. It describes how the intensity of light absorbed by a material is directly proportional to the thickness of the material and the concentration of the absorbing substance.
A swimming pool appears deeper than its actual depth due to refraction. When light travels from water to air, it bends away from the normal, making objects underwater appear higher and deeper than they actually are when viewed from above ...
The color of a star tells us about its temperature. Stars emit light across a spectrum, and their color corresponds to the temperature of their surface. Hotter stars appear bluish-white, while cooler stars appear reddish. This relationship between color and ...
Energy in reflected light does not depend on the angle of incidence. The amount of energy reflected remains constant regardless of the angle at which light strikes a surface. This principle is consistent in optics, where the angle of incidence ...
A watchmaker uses a magnifying lens to see the fine parts of a watch. This tool helps magnify small details, making it easier to inspect and work on intricate components such as gears, springs, and tiny screws with precision.
