**Calculating Internal Resistance and Terminal Voltage using Two Methods****Calculating Internal Resistance and Terminal Voltage using Two Methods (Multiple Resistors)****Solving for EMF using Two Methods**

The battery is measured from terminal to terminal and observed to have an electric potential difference of 6.25V.- Using the traditional terminal voltage formula method:
- What is the EMF?
- If the external resistor is replaced with a resistor of 4.4$\Omega$, what is the new voltage of the battery?

- Using the voltage divider method:
- What is the EMF?
- If the external resistor is replaced with a resistor of 4.4$\Omega$, what is the new voltage of the battery?

- Using the traditional terminal voltage formula method:
