Question

in this figure shown the power generated is maximum when y=5 omega then R is​

Answer 1

Answer:

For maximum power in the given resistor y = 0 ohm

Explanation:

As we know that power generated through given Resistance R is maximum

so power across the resistance is given by the formula

$P = i^2 R$

now we know that current in the circuit is given as

$i = \frac{10}{2 + y + R}$

so we have

$P = (\frac{10}{R + y + 2})^2R$

now in order to maximum this value we have to maximum the current

So we have

y = 0
