Question

What will be the equivalent resistance of circuit shown in heart figure betwern A and B?

Answer 1

Answer:

B) 10 ohms

first 2 resistors are in series

therefore , equivalent resistance of them is 10 + 10 =20 ohms

next 2 resistors are also in series

therefore , equivalent resistance = 20 ohms

they both are parallel to each other

therefore , equivalent resistance =1/20 + 1/20 = 1/10

therefore , resistance = 10 ohms
