What resistance must be placed in parallel with
a155-w resistor to make
theequivalent resistance 115-w?

A resistance of 445.625 ohm must be added in parallel

Explanation:

Here unit of resistance is given watt which will be ohm

We have given equivalent resistance R = 115 ohm

Resistance of one resistor

We have to find the value of

For parallel combination equivalent resistance is given by

So

So a resistance of 445.625 ohm must be added in parallel

for this one it would be d bump/forearm pass

hey , the answer is c
