Question

Under what condition, the current drawn from the cell is maximum?&#8203;a)R = rb)R &#62; rc)R = 0d)R &#60; rCorrect answer is option 'C'. Can you explain this answer?

Answer

The maximum current can be drawn from a cell if the external resistance R = 0.

When current is to be drawn at max then the conducting wire rating comes high such that resistance is less.

Resistance R = rho x l/a

Rho = resistivity constant

L=length

a=area of cross-section

Hence, if the area of cross-section increases resistance decreases by increasing the rate of current to flow.

Answer

Yes when R=0 because in this condition there is no barriour in flowing current . So, current can easily flow and hence current in circuit is maximum....

Answer

Maximum current drawn means maximum power and it is when external resistance is equal to internal resistance and also in the case in which external resistance is equal to zero....

Answer

☺Ans. C is correct .for a cell I = E/(R+r) so option【1】. for R=r I = E / 2r or =E/2R 【2】. for R>r I` =E/(2r + x) where R = r+x>r 【3】 for R=0. I`` =E/r. which is > I` and also >I`` . so...ans. is C

Answer

The correct answer is b) R = 0.

According to Ohm's Law, the current drawn from a cell is given by I = V/R, where V is the voltage of the cell and R is the resistance in the circuit.

When R = 0, the resistance in the circuit is zero, which means there is no resistance to the flow of current. In this case, the current drawn from the cell will be at its maximum value, as there is no opposition to the flow of electrons.

Answer

Current is inversely proportional to resistance
