Exam questions on Series and parallel circuits

1. A student in Mumbai builds a series circuit containing a 9.0 V battery and two lamps, X and Y. An ammeter next to the battery reads 0.30 A, and a voltmeter connected across lamp X reads 3.5 V.
   Calculate the resistance of lamp X.2 marks
2. A student in Lima is drawing a circuit diagram for a model house. Two identical lamps are connected in parallel to a 12 V battery, and a switch controls both lamps. An ammeter in the wire next to the battery reads 1.0 A.
   Calculate the current through one of the lamps.2 marks
3. A technician in Cairo has a 12 V supply, a 4.0 Ω resistor and an 8.0 Ω resistor.
   The two resistors are connected in series to the supply. Calculate the current in the circuit and the potential difference across the 8.0 Ω resistor.3 marks
