1. There are 3.3V passing through an orange power supply cable, and there are 0.25 ohms of resistance in the orange wire. How much power is supplied to the orange wire by the power supply?

Voltage (V) = 3.3 V

Resistance (R)= 0.25 ohms

Power (P) = V^2 / R

Replacing with the values given:

P = (3.3)^2 / 0.25 = 43.56 W

Answer: 43.56 Watts
