Thirty six cells each of emf 1.5 V and internal resistance `0.5 Omega` are used to send current through an external resistor of resistance `2 Omega`. What is the best mode of grouping them and the current through the external resistor

36 cells each of internal resistance 0.5 Omega and emf 1.5 V each are used to send current through an external circuit of 2 Omega resistance. Find the best mode of grouping them and the current through the external circuit.

45 cells each of internal resistance 0.4Omega and emf 2.0 V are used to send current through an external circuit of resistance 2.0 Omega . What will the best mode of grouping them for maximum current? Find the currnet in the external circuit.

36 cells each of internal reistance 0.5Omega and emf1.5V each are used to sent current an external circuit of 2Omega reesistance. Find the best mode of grouping them for maximum current of and the current through the external circuit.

Three similar cells, each of emf 2 V and internal resistance r Omega send the same current through an external resistance of 2 Omega when connected in series or in parallel. The strength of the current flowing through the external resistance is (A)

A battery of emf 6 volts and internal resistance 1Omega is connected in parallel to another battery of emf 8V and internal resistance 2Omega . The combination is then used to send current through an external resistance of 10Omega . Find the current through the external resistance.
