A 10.-ohm resistor and a 20. -ohm resistor are connected in series
to a voltage source. When the current through the 10.- ohm resistor
is 2.0 amperes, what is the current through the 20.-ohm resistor?
Answer:
B --> 2.0 A
the current going through the 10.-ohm resistor is what goes through 20.-ohm resistor
