The following circuit consists of 4 identical lamps connected to a 180 V battery. The lamps are controlled by three switches as shown below. Three instruments marked A1 , A2 and V are connected in the circuit to measure current and potential difference.
It is observed that when switch -1 and switch-3 are closed (switched on) and switch -2 is in open position; instrument A1 reads 15A. Based on the above observation; answer the following.
What is the resistance of each lamp?
Suppose switch-3 is open and switch-1 and switch-2 are closed. Find the reading of voltmeter (V1) and two ammeters (A1 and A2). What is the reading of A1 and A2 if switch-1 is open?
What is the reading of A2 when switch-2 is open and switch-1 and switch-3 are closed?
What is the energy consumed if all three switches are switched on for 30 minutes.
