Question

When an open circuit occurs ina parallel branch, the total resistance decreases?

Answer 1

Answer:

As you can see, when an open occurs in a parallel branch, total circuit resistance increases and total circuit current decreases. A short circuit in a parallel network has an effect similar to a short in a series circuit

Answer 2

Answer:

when an open occurs in a parallel branch, total circuit resistance increases and total circuit current decreases. A short circuit in a parallel network has an effect similar to a short in a series circuit.
