Questions: RT = k Ω a. 8 b. 902 c. 9028021

Solution Steps

• The circuit contains three resistors: \( R_1 = 800 \, \Omega \), \( R_2 = 1.2 \, k\Omega \), and \( R_3 = 0.9 \, M\Omega \).

• Convert \( R_2 \) and \( R_3 \) to ohms:
  • \( R_2 = 1.2 \, k\Omega = 1200 \, \Omega \)
  • \( R_3 = 0.9 \, M\Omega = 900,000 \, \Omega \)

• The resistors \( R_1 \), \( R_2 \), and \( R_3 \) are connected in series.

• For resistors in series, the total resistance \( R_T \) is the sum of the individual resistances: \[ R_T = R_1 + R_2 + R_3 \] \[ R_T = 800 \, \Omega + 1200 \, \Omega + 900,000 \, \Omega \] \[ R_T = 902,000 \, \Omega \]

• Convert \( R_T \) to \( k\Omega \): \[ R_T = 902,000 \, \Omega = 902 \, k\Omega \]
