QUESTION 6 5 pointsSave Answer The circuit below shows 2 batteries and 3 equal resistors. E1 35.8 volts, and E2-19.3 volts. Each resistor is 20.4 ohms. The circuit below shows 2 batteries and 3 equal resistors. E17 35.8 volts, and E2=19.3 volts. Each resistor is 20.4 ohms Find the power P2 dissipated in the resistor R2. Enter your answer in Watts. R1 2 R2 3 R3 58%

Explanation / Answer

Here,

Here,

for the current flowing through the R2

current through R2 = E2/R2

current through R2 = 19.3/20.4 A

current through R2 = 0.946 A

Now , for the power dissipated through R2

power dissipated through R2 = I2^2 * R2

power dissipated through R2 = 0.946^2 * 20.4

power dissipated through R2 = 18.26 W

the power dissipated through R2 is 18.26 W
