A voltmeter.
Thermometer is the instrument used to measure average thermal energy.
A dynamometer is a common instrument used to measure kinetic energy. It is designed to quantify the force or torque produced by an engine, motor, or other mechanical system.
The instrument used to measure average thermal energy is called a calorimeter. It is used to measure the heat released or absorbed during a chemical reaction or a physical change.
Collisions of electrons with other particles in a circuit can result in energy loss in the form of heat. This occurs due to resistance in the circuit, which causes a portion of the electrical energy to be converted into thermal energy. The charge of the electrons remains constant during these collisions.
When a positive charge moves due to a nearby negatively charged object, potential energy is converted into kinetic energy as the positive charge moves closer to the negative object. The potential energy decreases as the positive charge moves towards the negative charge due to the attractive forces between them. This energy change is responsible for the movement of the positive charge.
No; electron-volt is a measure of energy, not of voltage (or potential).
The term is electric potential. It is a measure of the potential energy of a unit positive test charge at a specific location in an electric field.
Electrical energy is used to charge a cell phone. When you plug your phone into a charger, the electrical energy is converted into chemical energy stored in the phone's battery. This chemical energy is later converted back into electrical energy when you use the phone.
The measure of the potential energy of an electric charge is called electric potential. It is defined as the work done per unit charge in bringing a test charge from infinity to a specific point in an electric field. The unit of electric potential is the volt.
To measure the change in energy per unit charge across a resistor, you can use the formula E = VQ, where E is the energy, V is the voltage across the resistor, and Q is the charge passing through it. By measuring the voltage across the resistor and the charge passing through it, you can calculate the energy per unit charge.
A frequency meter is the instrument that is used to measure the amplitude of sound. It reads the energy from a sound wave.
The measure of energy provided to charge an object is typically given in joules (J). It represents the amount of work done to move a unit of electric charge (coulombs) through an electric potential difference. The formula to calculate this energy is E = QV, where E is the energy in joules, Q is the charge in coulombs, and V is the potential difference in volts.
