Question

Three 3 Ω resistors P, Q and R are connected as shown in the figure. Each of them dissipates energy

and can withstand a maximum power of 27 W without melting. Find the maximum current that flows

through the resistor P.​

Answer 1

Answer:

If they are connected in series:

Explanation:

R=3 ohm

P=27 W

now we know that P=I²R

i.e 27=I²×3

I²=9

I=√9

I=3A
