The voltage on the orange power supply cable is 3.3 V and its resistance is 0.025 ohms. How much power is supplied from the power supply to the orange wire?
Data: U (voltage on the orange power supply cable) = 3.3 V; R (orange cable resistance) = 0.025 ohm.
The power that is supplied from the power source to the orange wire can be calculated using the formula: P = U * I = U * U / R = U ^ 2 / R.
Let’s make the calculation: P = 3.3 ^ 2 / 0.025 = 435.6 watts.
Answer: 435.6W was supplied to the orange wire from the power supply.
