How can two cells of 1.5V each can be connected to get 3V?
Parallel connection of cells
Series Connection of Cells
Without Joining them
Joining the same terminals of cells
Series Connection of Cells = Voltage of Cell1 + Voltage of Cell2
Equivalent Cell = 1.5 +1.5 = 3V
i current flows through a circuit when 10 cells are connected in series. How many same cells should be connected in parallel to get the same current
A 12 W resistor is connected in series with a cell of emf 1.5 V and negligible internal resistance (or terminal voltage 1.5 V). How must a 4 W resistor be introduced in the circuit, so that the current drawn from the cell is 0.5 A?
What will happen if you directly join the two terminals of a cell without connecting them to a switch or a bulb? [1 MARK]
