HURRY PLEASE
Three resistors of 3.0 9, 8.0 2, and an unknown resistance are
connected in series across a 9.0-V battery. If the current through the unknown
resistance is measured to be 1 A, answer the following questions.
a. What is the current through the 3.0-Q resistor?
b. What is the equivalent resistance of the circuit?
c. What is the potential difference across the 3.0-0 resistor?
