Question

Напряжение на клеммах аккумулятора при его зарядке током 6 А равно 9 В , а при разрядке током 4 А оно равно 7 В. Найдите ЭДС аккумулятора (В)

Answer 1

E=U2I1-U1I2/I1-I2=7*6-9*4/6-4=3В

Answer 2

Calculation of Battery EMF (Electromotive Force)

To find the EMF (Electromotive Force) of the battery, we can use the equation:

EMF = Voltage during charging - Voltage during discharging

Given that the voltage on the battery terminals during charging with a current of 6 A is 9 V, and during discharging with a current of 4 A is 7 V, we can calculate the EMF of the battery as follows:

EMF = 9 V - 7 V = 2 V

Therefore, the EMF of the battery is 2 V.

Please note that the search results did not provide specific information about the type or characteristics of the battery. The calculation assumes a simple battery model where the EMF is constant regardless of the charging or discharging current.
