Electrical Power

Electrical power 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 the circuit. The formula for calculating electrical power is:

Power (P) = Voltage (V) x Current (I)

Where:

• Power (P) is measured in watts (W)
• Voltage (V) is measured in volts (V)
• Current (I) is measured in amperes (A)

Electrical power is a crucial concept in understanding the functioning of electrical devices and circuits. It helps in determining the energy consumption and capacity of electrical systems.
