Power is calculated using the following rule:
Power = voltage x current
From Ohm's law:
Voltage = current x resistance ............> current = voltage / resistance
Therefore, the rule of power can be written as:
power = voltage x (voltage / resistance)
power = (voltage^2) / resistance
From the givens, we have voltage = 3.3 volts and resistance = 0.025 ohms.
Substitute in the equation to get the power as follows:
power = (3.3 ^2) / 0/025
power = 435.6 watt
