Electronic 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. |

Answer» (a) they draw more current which is inversely proportional to the voltage. Electronic motors draw more current which is inversely proportional to the voltage, therefore, more heat H = I2Rt is generated. |
