Work, Energy, and Power

Our solar system’s major renewable energy source is solar energy. Although the phrase commonly refers to the visible light of the sun, it is a type of energy radiated by the sun that includes light, radio waves, and Xrays. As oil prices rise and other energy sources become rare, countries are increasingly looking for safe, […]

Introduction PWM (Pulse Width Modulation) is a technique for converting an analogue signal to a single digital bit. A duty cycle and a frequency are the two basic components that describe the nature of a PWM signal. Pulse width modulation PWM (pulse-width modulation) or PDM (pulse-duration modulation) is a technique for reducing the average power

We use electrical energy to power various electrical devices in our daily lives. The quantity of energy transmitted in an electric circuit for a certain period is known as electric power. Energy is defined as the ability to carry out any task. Work is done when a force moves an object from one point to

Non renewable energy sources are energy sources that will not be replenished in the future. This implies it can’t be replenished once it’s been spent and will ultimately run out. Non-renewable energy is derived from non-renewable resources that can be supplied at a rate far slower than they are consumed. Because the rate of replenishment

Energy is primarily defined as a system’s ability to perform and cause events to occur. When it comes to objects, energy is primarily a quality that cannot be created or destroyed but may be transmitted. Natural resources such as thermal energy, nuclear energy, sunshine energy, and other forms of renewable energy are abundant throughout the

Mass-energy relation expresses that each article has specific energy even in a fixed position. A fixed body doesn’t have active energy. It just has expected energy and likely compound and nuclear power. As indicated by the field of applied mechanics, the amount of this multitude of points is more modest than the result of the particle’s

In physics, power is an important quantity that relates to Work and Energy. Physics defines work done as the product of an object’s displacement and external force applied. The capacity to get the work done is called energy. However, we need work done and time as the driving units to define power. There are many

Every object around us possesses mechanical energy. Whether it is a hand that swings the tennis racket or a rotating fan in our living room, they all move due to mechanical energy. All the simple and complex systems that exert force – use mechanical energy to get the work done. An aeroplane takes off by

Machines that are used to do useful work by converting heat into mechanical energy are known as Heat engines. These heat engines receive heat from the ignition of fuel, coal, petrol, or other energy sources. There are three parts of heat engines – source, or hot reservoir, the working body, and cooler or sink or

Power is defined as the amount of work done per unit of time. In an alternating current circuit, power is given by the product of voltage and current. However, values of voltage and current change every instant in an AC circuit. Therefore, the power in an AC circuit at any instant of time is calculated
