Question

Can someone please help?

Answer 1

What is the current in a series circuit that has two resistors
(4.0 ohms and 7.5 ohms) and a power source of 9.0 volts?

Answer 2

When resistors are in series, their effective resistance is:\[R _{eff}=R _{1}+R _{2}\]. Current is given by Ohm's Law:\[I=\frac{ V }{ R }\]where I is current; V is voltage; and R is resistance.

Answer 3

Do you see how to solve the problem now?

Answer 4

i have options of
2.6 amps
12 amps
1.6 amps
0.78 amps

Answer 5

You can use the two formulas I gave you to find the answer.

Answer 6

i get .3

Answer 7

never mind i get .78 thanks a million

Answer 8

That's correct, and you're welcome.
