what effect does the voltage of a battery have on the amount of current ?
Answers
Explanation:
Voltage is the difference in charge between two different points. The more the voltage, the greater the flow of electrical current. The current experiences a resistance to its flow; the amount of voltage determines the extent to which the current overcomes this resistance.
Answer:
Explanation:
the current in a circuit is directly proportional to the electric potential difference impressed across its ends and inversely proportional to the total resistance offered by the external circuit. The greater the battery voltage (i.e., electric potential difference), the greater the current. And the greater the resistance, the less the current. Charge flows at the greatest rates when the battery voltage is increased and the resistance is decreased. In fact, a twofold increase in the battery voltage would lead to a twofold increase in the current (if all other factors are kept equal). And an increase in the resistance of the load by a factor of two would cause the current to decrease by a factor of two to one-half its original value..
The table below illustrates this relationship both qualitatively and quantitatively for several circuits with varying battery voltages and resistances.
