1.Which arrangement of cells, series or parallel, gives the higher voltage?
2.If a dry cell, after considerable use, has an e.m.f. of 1.5 volts and furnishes 5 amperes on short circuit, what is the internal resistance of the cell?
3.Six dry cells, each with an e.m.f. of 1.5 volts and an internal resistance of 0.3 ohms, are connected in series. The external resistance is 0.2 ohm. What is the current through the circuit?
4.If the six cells in question 3 are connected in series with an external resistance of 20 ohms, what is the current in the circuit?
5.If the six cells in question 3 are connected in parallel with an external resistance of 0.2 ohm, what is the current in the circuit?
