Can the terminal voltage 3u )5q: r)bbzszye+ke of a battery evedhbaw he+27b6 r exceed its emf? Explain.
参考答案:
The terminal voltage of a
battery can exceed its emf if the battery is being charged – if current is
passing through the battery “backwards” from positive pole to negative
pole. Then the terminal voltage is the
emf of the battery plus the voltage drop across the internal resistance.
