Two resistors of resistance 230 O and 340 O are connected in series (one after the other). A potential difference of 20 V is applied between the ends of the chain. a) What is the total resistance of the circuit (in O)? Give your answer as a whole number. b) Calculate the current flowing through the circuit (in A). Gve your answer to 3 d.p. and use this value to that degree of accuracy, in subsequent calculations, if needed. c) Calculate the potential difference across the 230 O resistance. Give your answer in volts to 2 d.p..
