and another voltage drop acrossR 2 (from orange to purple). The voltage drop across both resistors (red to purple) is

12 V. What are the voltage drops across each resistor?

Using Ohm’s law, we can find the voltage drop across each resistor.

V 1 =IR 1 =I( 10. 0 Ω)andV 2 =IR 2 =I( 6. 0 Ω)

The total voltage drop must be
