use voltage division to find the voltage across r3, positive at the top.

Answer :

V1 = (1.2 A)(2 ) = 2.4 volts is the voltage across R1.V2 = (1.2 A)(3 ) = 3.6 volts is the voltage across R2.V3 = (1.2 A)(5 ) = 6.0 volts is the voltage across R3.

How can the voltage across be determined?

We can use Ohm's Law (V = I x R) to determine actual voltage drops over each resistor once we have the amperage for such circuit (remember that the amperage doesn't really change inside a series circuit).

How can I calculate the voltage drop between two resistors?

According to Ohm's Law, V=I*R, where V stands for voltage, I for current, and R for resistance.The power loss across each resistor in a series circuit will be inversely correlated with its size.The voltage drop over each resistor in a parallel connection will be equal to the voltage coming from the power source.
