We should never connect both terminals of a cell without connecting an appliance in a circuit. Justify.
Answers
Because if you connect both terminals without “an appliance” in between them to form a circuit, then the cell will produce the highest electrical current which it can provide and such uncontrolled release of energy may cause either the cell to overheat, or the wire you use to connect cell’s terminals to overheat as well. Depending on cell’s actual amount of energy stored and actual capacity to release that energy (it’s own internal electrical resistance) this may end up causing fire, explosion of the cell, or cell’s body melting with release or leak of chemicals which often are toxic or dangerous to handle like acids or strong bases, or heavy metals like lead, lithium, etc.
The “appliance” acts like an electrical resistor which limits the maximum amount of current flowing through cell’s terminals. So by choosing an “appliance” with very high power consumption or very low internal resistance, the results might be the same of overheating, melting, leaking or catching fire. A hair dryer for instance is a typical household appliance with those characteristics of very low internal resistance and attempting to connect it to a “cell”, usually meaning a DC battery, is not a good idea; the dryer will not work at all but just cause an overload or “short circuit” to the cell
