Hey there; I would like some assistance.

23 For the circuit below calculate: 12V 20 342 a the total resistance in the circuit [4] b the current flowing through the 12V d.c. supply [2] c the potential difference across the 2 $2 resistor [2] d the potential difference across the 1$2 resistor 2] e the current flowing through the 242 resistor [2] f the power dissipated in the 3 $2 resistor.
