4 The diаgrаm shоws а circuit that includes a battery, an ammeter, a vоltmeter and three different resistоrs. Refer to addendum Figure 4.1 (a) State what is meant by the term electric current. (1) (b) Give the name of the particles that flow if there is an electric current in a wire. (1) (c) (i) Give the voltmeter reading. (1) (ii) State the formula linking voltage, current and resistance. (1) (iii) Calculate the resistance of resistor X. (3) (d) (i) Give the reason why the reading on the ammeter would be 16 mA. (1) (ii) Calculate the resistance of resistor Y. (4) (e) Resistor X and the voltmeter are removed from the circuit, leaving a break in this part of the circuit. Explain how the current in the battery changes when these components are removed. (2) (f) (i) State the formula linking energy transferred, charge and voltage. (1) (ii) Calculate the charge transferred through the cell when the cell transfers 4.5 J of energy. (3) (Total for question 4 = 18 marks)
