Question

Refer to the following series circuit: + R R, = 17.2 V R, = 52 1:11 V = 15V R, 1 I Calculate the total power developed in the circuit. P= Choose... watts Choose... 15 120 98 Submit Answer Skip C Notes​

Answer 1

Series connection

• R=R1+R2=10+5=15
  `\Omega`
• V=15V

Now

`\\ \rm\Rrightarrow P=(V^2)/(R)`

`\\ \rm\Rrightarrow P=(15^2)/(15)`

`\\ \rm\Rrightarrow P=15W`
