Question

Determine the equivalent resistances between A and B

Answer 1

Answer:

1.3

Explanation:

first it is parallel,then

• R = 1/r+1/r+1/r..........
• Here,the voltage is equal.
• so, 1/9+1/9+1/9 = 1/3 volts.
• Now,second we have parallel.
• so, 1/3+1/3+1/3 = 1 volts.
• Now,they are in series.
• so,R = r+r+r.
• That is, 1/3+1 = 4/3.
• Hence,1.3 volts is the equivalent resistance.
