Electric Circuit Elements 17. Design a circuit that has a single resistor connected in series. Choose a resistor
that will provide 20 W of power from a 40 V power source.
Use the instructions provided in step 1 to build the circuit.
18. Calculate the current through and voltage drop across each resistor, and record
the values in data table 7.
19. Using the ammeter and voltmeter, determine the current through and voltage
drop across each resistor. Record the values in data table 7.
