Homework #5 Problem 23.19- MC 1 of 8 Part A Constants In the section of the circuit shown, the current 12 2.25 A (Figure 1) How much current is flowing through the resistor R? Express your answer to three significant figures and include the appropriate units View Available Hint(s) 11 = 0.250 A Correct PartB What is the value of resistor R Express your answer to three significant figures and include the appropriate units. View Available Hint(s) Figure 1 of 1 R- 10 2.5 A Submit 1001 X Incorrect; Try Again Next > Provide Feedback

Explanation / Answer

Part A:

from junction rule, current through R=2.5-2.25=0.25 amperes

Part B:

value of resistor R will be such that potential difference across R and 100 Ohm resistor will be equal because thet are in parallel

Therefore, 0.25*R=2.25*100

R=900 Ohms
