Two bulbs each of resistance 2.0omh connect in parallel with a battery.
Calculate the current flowing through any of the bulb if the voltage of the 0.2v.
i) Calculate the total emf of the cells.
ii) What would be the total emf of the cells if the cells were connected parallel.
To calculate the current flow through any of the bulbs, we can use Ohm's Law, which states that the current flowing through a conductor is directly proportional to the voltage across it and inversely proportional to its resistance.
i) Calculate the total EMF of the cells:
To calculate the total electromotive force (EMF) of the cells, we need to know the individual voltage of each cell. However, the information provided only mentions the voltage of 0.2V. To calculate the total EMF of the cells, we need to know the number of cells connected in the battery.
ii) What would be the total EMF of the cells if the cells were connected in parallel:
When cells are connected in parallel, the total EMF remains the same as the individual EMF of each cell. This is because, in parallel connection, the voltage across each cell remains the same while the current is divided among them. So, the total EMF would be the same as the individual EMF of each cell.
