Objective: i) To calculate the current in a series circuit and the potential difference across
each resistor connected in series.
a) Design a circuit including a source and two identical resistors in series so that the
current through the circuit measures 0.40 A.
Circuit diagram.
b) Use the link given to construct the circuit according to your design, verify measuring
the values of the resistors and the current through the circuit. Also measure the
voltage across the battery and that across each resistor.
