Why do electric motors have instant torque?
As the electric current travels through the motor within a magnetic field, it generates a force. The more current applied, the more the motor will spin. … But at zero RPM, all of the electricity the motor creates from the time electric power is applied becomes instant torque—without any back EMF to reduce its output.
How does acid produce electricity?
Acids undergo dissociation in aqueous solution to form H+ ions. When electricity is passed through an aqueous solution of an acid, the H+ ions reach the cathode and each H+ ion picks up one electron from the cathode to form H2 gas. Because of this reaction, an aqueous solution of acid conducts electricity.
Can you cover an electrical outlet?
