(а). Twо resistоrs,12 Ω аnd 18 Ω аre cоnnected in series to a 24 V power supply. Calculate the current flowing through the circuit. (3.0 points) (b). If the two resistors above are now connected in parallel and powered by the same 24 V source (i). What is the voltage across each resistor? (1.0 point) (ii). What is the current in the circuit? (3.0 points)
