Electricalpower is the rate at which electrical energy is transferred by an electric circuit. It is measured in watts (W) and is the product of voltage (V) and current (I) in a circuit.
Key Concepts
Voltage: The force that moves electric charges through a conductor. It is measured in volts (V).
Current: The flow of electric charges through a conductor. It is measured in amperes (A).
To calculate the electricalpower in a circuit, you can use the formula: P = V x I, where P is the power in watts, V is the voltage in volts, and I is the current in amperes.
Plan and carry out investigations that demonstrate the chemical and physical processes that form rocks and cycle Earth’s materials (e.g., processes of crystallization, heating and cooling, weathering, deformation, and sedimentation).
