The diagram looks exactly like that. I live in Scotland and the course work is a bit different. I am doing higher physics and the key area is called Electrical Sources and Internal Resistance.
Thanks for the reply. I had a look and I still can't find any relevant equations to use. If I had an equation I would be able to work it out from there. I tried to upload a photo but it kept denying me.
Homework Statement
A cell has an e.m.f =1.5v and Internal Resistance = 0.75Ω is connected as shown in the following circuit ( circuit has 3Ω resistor under the battery)
(I) Calculate the reading on the voltmeter.
(Ii) what is the value of the "lost volts" in this circuit?
Can anyone help me...
