8. 0/1 points. l Previous Answers SerCP7 18. P. 010 soln My Notes Ask Your Teacher Two resistors, A and B, are connected in parallel across a 7.0 V battery. The current through B is found to be 1.0 A. When the two resistors are connected in series to the 7.0 V battery, a voltmeter connected across resistor A measures a voltage of 3.8 V. Find the resistances A and B. Your response differs from the correct answer by more than 10%. Double check your calculations. 2 RB 6.57 Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. 2 Submit Answer Save Progress Practice Another Version 9. -l 1 points SerCP7 18.
