Sahay Sir > Question Answers > In Fig.` the voltmeter and ammeter shows are ideal. Then voltmeter and ammeter readings
A cell of internal resistances r is connected to a load of resistance R . Energy is dissipated in the load, but some thermal energy is also wasted in the cell. The efficiency of such an arrangement is found from the expression ( Energy dissipated in the load )/( Energy dissipated in the complete circuit) Which of the following gives the efficiency in this case?

Three similar light bulbs are connected to a constant to a constant voltage dc supply as shown in `Fig . Each bulb operates at normal brightness and the ammeter ( of negligible resistance) registers a steady current. The filament of one of the bulbs breaks. What happens to the ammeter reading and to the brightness of the remaining bulbs?
