Question

A series circuit contains a 9-volt battery, a 3-ohm resistor and a 2-ohm resistor. What is the voltage drop across the 2-ohm resistor?


3.4 V

3.6 V

3.8 V

Answer 2

Gotta use the ohm law.

V=IR
v=voltage
I=current
R=resistance

They tell you the voltage is 9 and that the resistance is 2 and 3.

You first have to calculate the current.

9=I(5)

To get I, you must do 9/5 which is 1.8 amps

Now..to get your voltage drop for 2 ohm resistor..

Just do 1.8 x 2..
