Question

Two resistance of 30 ohm and 20 ohm are
connented in series and then parallel to a 150 v supply.Find the power taken in each case?
​

Answer 1

Step-by-step explanation:

For series

Reff=20+30=50 ohm

V=150

Power=V²(Reff)

Power=(150)²(50)

Power=1.125×10⁶

For parallel

Reff=12 ohm

V=150

Power=(150)²(12)

Power=2.7×10⁵

hope it helps
