If a large enough force is applied to a solid object the shape of the object can change. This change…
Waves are a transfer of energy that can be described as vibrations (or oscillations) about a rest point. Below is…
Kirchhoff’s First Law Kirchhoff’s first law is a consequence of the conservation of charge and states that: The sum of…
Resistivity is a property of a material that quantifies its resistance to an electric current flowing through it. The resistivity…
Electrical Power (P) – the rate at which electrical energy is transferred. This is exactly the same as mechanical power…
Resistance (R) – the resistance of a device is the ratio of the voltage applied to it, to the current…
Electric Charge Electric charge is a property of some particles that causes them to experience a force in an electromagnetic field.…
Power – the rate at which work is done. From this definition we have the following equation: Where P is…
