To find the total resistance of resistors connected in series, you simply add their resistances together.
Given that there are three resistors of 15.0 Ohms each:
\[
R_{\text{total}} = R_1 + R_2 + R_3 = 15 \, \Omega + 15 \, \Omega + 15 \, \Omega = 45 \, \Omega
\]
Therefore, the total resistance of the circuit is **45 Ω**.

\[
R_{\text{total}} = R_1 + R_2 + R_3 = 15 \, \Omega + 15 \, \Omega + 15 \, \Omega = 45 \, \Omega
\]
Therefore, the total resistance of the circuit is **45 Ω**.
