Observe the brightness of the bulb and measure the current that flows through a single bulb asshown in the circuit in situation 1.2. Observe the brightness of the bulb and measure the current that flows through a single bulb asshown in the circuit in situation 1 when battery’s voltage or bulb resistance is changedrespectively.3. Measure the current that flows in ammeters A, A 1& A 2in situation 2 when different combinationsof the switches S 1, S 2& S 3are thrown down.4. Observe the brightness of bulbs 1 and 2 when different combinations of the switches S 1, S 2&S 3are thrown down and as the battery’s voltage is varied.5.
