Great video! One question, at around 36:45 you mention that in the experiment you measure terminal pd. Does the voltmeter not measure EMF as the two points are connected in parallel across the cell and internal resistance portion? Or am I getting mixed up with my definition of terminal pd?
@fungamingtv1111
@fungamingtv1111 5 ай бұрын
Emf is the voltage before it leaves the cell, while pd of the cell is the voltage leaving the cell I believe. So emf is greater than pd of terminal. Pd is what you would measure with the voltmeter, while emf is the pd you would have if there was no internal resistance.(unless I'm mistaken lmao)

Hello; Thank you for these videos, they are much appreciated, I do have a few queries however. Firstly, how much of the content of the OCR specification are covered in your videos? And secondly; On your previous video of this module "Current and Charge", you stated that in an electrolyte solution, positive ions move to the anode and the negative ions go to the cathode. Would it be possible if you could explain what you meant by this? My resources regarding the OCR material stated that the positive ions go to the negative terminal and the negative go to the positive- Many thanks and my apologies for the hassle.

@@zhelyo_physics Thank you kindly. Much appreciated. One more query, apologies: Do specific conditions of the electrolytic system (like polarity electrolyte composition, potential difference. eg.) and the electric field established by the applied potential alter whether or not the positive ions move to the positive or negative terminal in an electrolyte? Or is it a constant that the positive ions move to the positive terminal? My material says "The positive ions move towards the cathode, accepting an electron, and the negative ions move towards the anode, donating an electron to flow in the metal part of the circuit", and I admit I'm a bit confused- I apologise for my confusion. Many thanks. :)

@amenmolla7203
@amenmolla7203 9 ай бұрын
The voltage across a closed loop is 12 (Kirchoff's 2nd law) and we calculated 9.3 volts which is on the same loop so since it should add up to 12, we subtract 9.3 from 12 to find the remaining available voltage

At the end when you do he themistor and LDR examples, if you know that the resistance of the thermistor goes down, can you just straight away say that the voltage goes down using the potential divider equation in the formula book? Since the ratio of R2 and R1 + R2 decreased. Or do you have to go through each of those steps you stated?

in 30:36 how did you get that the voltage of the resistor D is 14V ? Would it not be 16V as the total emf is the sum of potential differences in one closed loop so if we look at the first closed loop the total is 24V and this would also be the same for the second closed loop so the voltage of D would be 24 - 8 = 16V right ?

I meant regarding what you said in the video. You said "lost energy per unit charge". This does seem more correct now when I think about it since voltage is energy/charge. But if we follow the definition which shows on the screen then shouldn't it be energy per unit current? Also, resistance isnt a measure of voltage lost though. The measure of that is voltage itself (since it is the work done by the charge carriers on the resistor and therefore energy lost). The equation for lost volts is Vlost = Ir which equals W/Q because Vlost isnt resistance you wouldn't you use these equations instead of a one for resistance (i.e. r= Vlost/I) Could you answer this please? I dont mean to be rude.
