Series circuit diagram with a 12 V battery and three resistors (10 Ω, 20 Ω, 30 Ω) connected in a single loop with current I flowing through all.
1.

A series circuit contains three resistors (R1=10 ΩR_1 = 10\ \Omega, R2=20 ΩR_2 = 20\ \Omega, R3=30 ΩR_3 = 30\ \Omega) connected to a Vsource=12 VV_{source} = 12\ \text{V} battery. What current flows through the circuit?
