Solve the following questions given below:
Question I: Calculate the equivalent resistance of three resistors R1 in series with the combination of R2 and R3 in parallel if R1=10W, R2=100W, and R3=33W.
Question II: If a 12 Volt battery is placed across the three resistor combination in the previous problem, find the currents through each resistor.
I need tutor help to solve the above questions. Thank you.
