Two cells of EMF 2E and E and internal resistance 2r and r respectively are connected in parallel. Obtain the expression for the equivalent EMF and the internal resistance of the combination??

Question

Susmita · Answer

Equivalent internal resistance is simply r eq =r1r2/(r1+r2)=2r/3 For parallel connection total current I=I1+I2 Or,E eq /r eq =E1/r1+E2/r2 Or,E eq =r eq E1/r1+r eq E2/r2=(r2E1+r1E2)/(r1+r2)=4E/3
