- 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, 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, what is the new voltage of the battery?
