How is electrical power generally measured in circuits?

Electrical power is generally measured in watts, which is a unit that quantifies the rate of energy transfer or conversion in an electrical circuit. Power in electrical circuits is calculated by the product of voltage (volts) and current (amperes) following the formula P = V x I.

This means that watts represent the actual work being done by the electrical energy as it flows through the circuit. For instance, a circuit that operates at a higher voltage with a certain current will deliver more power than a circuit at a lower voltage under the same current.

Understanding power in watts is crucial for a BMET because it helps in assessing the performance and efficiency of biomedical equipment, ensuring they operate within safe limits and specifications.
