A V-volt battery is connected to a R-ohm resistor. Due to the flow of current, a total of N electrons pass through it in one minute. If the resistance is then changed to one that is R/2- ohms, what will be the number of electrons passing in one minute.

00:01 Hi, the equation says that here an equation we want to find here the current current in current through it we want to find here the current now i is equal to there is a electric current there is a year equation we are given here the two cases in the first case in a first case that is a electrical component there is a resistance of electrical component are constant resistance are is equal to here the constant value we are given here the resistance r value and we are also given here the potential difference you also given here the potential difference potential difference and you know by potential difference by v now in a second case the resistance is constant the distance value are constant donation value does not change here now the resistance here is r but potential difference but here the potential difference is changing from v to v by 2 in before case the potent difference value is v now in a second case the potential difference value is v by 2 now we want to find here the current we want to find here the current i here we take a current here i -dice we want to find here this current we know that the first case current we know to buy i we noted by i okay that we want to find here now we using the principle of ohoms law oh homeslow we are using the principle of oh homeslaw here oh homes say this the potent difference between the two ends of the two ends of the wire is equal to is equal to this proportional to the electric current passing through it and v is equal to ir this is rule we want to find here the current not taking current on a left hand side i is equal to v byr for a first case for a second case we put it here i -dice and here is a v by 2 and divided over r is equal to constant resistance is constant i -dice is equal to v by 2 r we take a one hub common and there's a v -bire also and we putting the i is equal v -brier value the v -bire value the v -bire is equal to i put it here there is the i by 2 and in the second case the current value is decreasing the hub this is the final answer to the question...

Question

A V-volt battery is connected to a R-ohm resistor. Due to the flow of current, a total of N electrons pass through it in one minute. If the resistance is then changed to one that is R/2- ohms, what will be the number of electrons passing in one minute.
