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.

A battery of 6 V internal resistance 0.5 Omega is joined in parallel with another of 10 V and internal resistnace 1 Omega . The combination sends a current through an external resistance of 12 Omega . Find the current through each battery.

A battery of emf 4 volt and internal resistance 1 Omega is connected in parallel with another battery of emf 1 V and internal resistance 1 Omega (with their like poles connected together). The combination is used to send current through an external resistance of 2 Omega . Calculate the current through the external resistance.

A battery of emf 6V internal resistance 5 Omega is joined in parallel with another cell of emf of 10V and internal resistance 1Omega and the combination is used to send current through a resistor of 12Omega . Calculate the current through each battery.

Two cells one of emf 1.4 V and internal resistance 0.6 Omega the other of emf 2.5. V and internal resistance 0.3 Omega are connected in parallel and the combination is connected in series with an external resistance of 4 Omega . What is the current through this resistance?
