Question

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?

A. 2.6 amps
B. 12 amps
C. 1.6 amps
D. 0.78 amps

Answer 1

the 4.0 ohms and the 7.5 ohms act like a single resistor of 11.5 ohms.

the current in the circuit is

(the supply voltage) / (the total resistance)

(9.0 volts) / (11.5 ohms)

0.783 (rounded)
