8. Design a circuit that has two resistors connected in parallel. Given that you have a 22.5 Ω equivalent resistance, calculate a power source voltage that will produce a current of 0.8 A. Record the resistance and voltage in data table 4. Use the instructions provided in step 1 to build the circuit.

9. Calculate the current through and voltage drop across each resistor, and record the values in data table 4.

10. Using the ammeter and voltmeter, determine the current through and voltage drop across each resistor. Record the values in data table 4.

In positive numbers less than 1, the zeros between the decimal point and non zero are significant
