Is the current through eight ohm resistor greater than six ohm resistor?
(e)

Answer to Problem 1SP
Yes, it is greater.
Explanation of Solution
The current through eight ohm resistor is greater than the current flowing through six ohm resistor since the eight ohm resistor is connected serially and the six ohm resistor is connected parallel.
Conclusion:
Yes it is greater.
