A 1000 watt supply to a battery spins it at a known RPM. Can the torque be calculated?

The torque can be calculated if you know the power (in watts) and the rotational speed (in RPM). The formula to calculate torque (T) when power (P) and rotational speed (n) are known is:

$$T=\frac{P}{2\pi \times \frac{n}{60}}$$

Where:

• ( T ) is the torque in Newton-meters (Nm)
• ( P ) is the power in watts (W)
• ( n ) is the rotational speed in revolutions per minute (RPM)
• ( \pi ) is the constant (approximately 3.14159)

So for a 1000 watt power supply and a known RPM, you can calculate the torque using this formula. Just plug in the values for ( P ) and ( n ) to get the torque.
