Hello,
could someone help me with this please. A battery of emf 12v and internal resistance 1.25 (Ω) is connected across an 8 Ω resistor. I have to calculate current through the voltage and terminal voltage...
Thank you so much

Hiya!
Have you tried using the equation for internal resistance:
Emf= lost volts + terminal p.d.

or

emf = V+ IR
where V is internal resistance, and R is the total resistance in the rest of the circuit

Have a go with this, and let me know if you get stuck. Hope this helps
