I have another question about motors as generators.
If I measure the resistance across the leads of a motor and they read 10 ohm, and the motor is labeled 9v...this would mean the motor at 9V = 0.9A Draw @ 8.1W.
If I am using the same motor as a generator to output the same in reverse, supplying a circuit of 6.8 ohm resistance 5.1V. 750Ma at 3.82W, The generator should be able to supply this circuit without burning out correct?
Is measuring the resistance across the leads of a motor an accurate way of calculating this?
and also is it a general rule of thumb that the circuit does not exceed the resistance rating of the motor? Thanks
