What is the power delivered to a circuit if the current is 2 amperes and the voltage is 10 volts?

• A. 5W.
• B. 20W.
• C. 15W.
• D. 25W.

Answer: (B)

To calculate the power delivered to a circuit, you can use the formula: Power (P) = Voltage (V) × Current (I). In this case, the voltage is 10 volts and the current is 2 amperes. Plugging these values into the formula gives: P = 10V × 2A = 20W. This confirms that the power delivered to the circuit is 20 watts. This formula is grounded in Ohm's law and is fundamental in electrical engineering, ensuring accurate calculations of power consumption. Understanding this relationship is essential for a Biomedical Equipment Technician, as it allows for adequate analysis of electrical devices and their energy usage.
