Question

Matt has a 3 ohm motor and a 25 ohm motor are wired in parallel with a 16 volt battery. which device uses the most power and how much power does it use?

Answer 1

When devices are connected in parallel, the power consumed by each device depends on its resistance. The 3 ohm motor uses the most power, consuming approximately 85.33 watts.

Step-by-step explanation:

When devices are connected in parallel, the power consumed by each device depends on its resistance. The power consumed by a device can be calculated using the formula: power = (voltage)² / resistance. In this case, the motor with a resistance of 3 ohms will consume more power than the motor with a resistance of 25 ohms. To calculate the power consumed by each motor, we can plug in the given values into the formula:

For the 3 ohm motor: power = (16 V)² / 3 ohms = 85.33 W

For the 25 ohm motor: power = (16 V)² / 25 ohms = 10.24 W

Therefore, the 3 ohm motor uses the most power, consuming approximately 85.33 watts.
