Best ResponseYou've already chosen the best response.3Do you know anything about Ohm's law?

Best ResponseYou've already chosen the best response.3Good, so lets's start. I'll leave part (a) for you.

Best ResponseYou've already chosen the best response.0Actually,I got part(b) also.

Best ResponseYou've already chosen the best response.3Ok, current in the circuit can be calculated by using the formula, \(\sf \boxed{\Large I=\frac{Emf}{r+R}}\)

Best ResponseYou've already chosen the best response.0I've no idea how to go about the rest :(

Best ResponseYou've already chosen the best response.3Potential difference across each resistor: You know the current flowing (I) now. use V=IR for each resistor. E.g. across 20 ohms resistor voltage drop will be 0.096*20

Best ResponseYou've already chosen the best response.0p.d across 20 ohm resistor is 1.92?

Best ResponseYou've already chosen the best response.0and the latter is 0.48?

Best ResponseYou've already chosen the best response.0i.e across the 5 ohm resistor.

Best ResponseYou've already chosen the best response.0and across the cell?

Abhisar

Best ResponseYou've already chosen the best response.3Ok, let's do the last one first... When the current is flowing, then the potential difference between the terminals of the cell < EMF and that potential drop V is given by, V= (emf of the cell)  Current X internal resistance. V= 2.5  0.096 X 1

Best ResponseYou've already chosen the best response.0that should be the p.d across the cell...

Best ResponseYou've already chosen the best response.3Nuuu...I explained it wrong earlier....chuck that from ur mind..

AaronAndyson
 one year ago
Best ResponseYou've already chosen the best response.0so p.d across the cell is?

Abhisar

Best ResponseYou've already chosen the best response.3Recall what we did to find the pd across resistors??? We multiplied their individual resistances with current flowing..Right?

Abhisar
 one year ago
Best ResponseYou've already chosen the best response.3Similarly, to find pd across the cell we will multiply the current with resistance of cell i.e. internal resistance...

Best ResponseYou've already chosen the best response.3Can you find it for me?/

AaronAndyson

Best ResponseYou've already chosen the best response.00.096*2.5 = p.d across the cell?

Best ResponseYou've already chosen the best response.0Internal resistance = 1 ohm

Abhisar

Best ResponseYou've already chosen the best response.3Internal resistance is given in the question and we calculated the current in 1st part :O

Best ResponseYou've already chosen the best response.0I know...Zoned out xD

AaronAndyson

Best ResponseYou've already chosen the best response.0Current is 0.096A and Internal Resistance is 1 ohm

AaronAndyson

Best ResponseYou've already chosen the best response.0Voltage drop = current*internal resitance right?

AaronAndyson
 one year ago
Best ResponseYou've already chosen the best response.0so 0.096 is the voltage drop?

Abhisar

Best ResponseYou've already chosen the best response.3\(\huge \checkmark\) Voltage drop across the cell
