2. Consider battery shown in the figure with an electromotive force value of E = 10.0[V] an internal resistance value 7'. The battery is then connected to the resistor having a value of R = 120.[Q]. After connecting the whole circuit shown below, the current value is 2.40[mA]. 1 0'") a. What is the value of the internal 1\"? b. What is the voltage value across the entire battery (meaning the voltage of the battery if the internal resistance r is considered)
