Electric motors operating at low voltages tend to burn out because |
|||
(a) |
they draw more current which is inversely proportional to the voltage. |
(b) |
they draw more current which is inversely proportional to the square root of the voltage. |
(c) |
they draw heat proportional to V2. |
(d) |
low voltage sets in electrical discharge. |
