Question

6. Calculate the equivalent resistance between
points X and Y of the circuit as given below.
(3 marks
(a) Calculate the readings in ammeter A and C
(b) Calculate the total resistance of the circuit​

Answer 1

Answer:

there is no ammeter shown

0.75ohm

Explanation:

3ohm resistors of each branch in series and the 3 branches are parallel

r of 3ohm branch= 3+3= 6 ohm

r of 1ohm branch = 1ohm

r of other 3ohm branch= 3+3= 6 ohm

all are parallel, so total resistance is

1/r= 1/6+1/6+1/1

1+1+6/6

8/6=4/3=1/r

r=3/4ohm=0.75ohm

hope it helps!
