Q1. A simple series circuit is set up is shown using a 24 V potential difference supply from a lorry battery, an ammeter which shows a constant 1.5 A, a 14 ohm resistor and a filament bulb.



(a) What is the current passing through the filament lamp?


(b) What is the potential difference measured by the voltmeter across the 14 ohm resistor ?


(c) What is the potential difference being measured by the voltmeter across the filament light bulb?


(d) Finally, what is the resistance of the filament light bulb?



Q2. A simple series circuit is constructed, consisting of a single cell supplying 3 V potential difference and two resistors in series of resistance 5 ohms and 10 ohms respectively.


(a) Draw the circuit, labelled appropriately.


(b) What is the total resistance of the circuit?


(c) Calculate the current flowing around the circuit, in amperes.
