Which of the following is a safety hazard of a 12-volt storage battery that lacks internal protection circuitry?
Touching both terminals with your hands can cause electrical shock
Shorting the terminals can cause burns, fire, or an explosion✓Richtige Antwort
RF emissions from a nearby transmitter can cause the electrolyte to emit poison gas
All these choices are correct
Erklärung
A lead-acid or lithium storage battery has very low internal resistance, so a short across the terminals can pass hundreds of amperes almost instantly, melting metal, igniting nearby material or rupturing the cell. Twelve volts across dry skin does not push enough current through the body to be the main hazard here.
