Question

What is the current in a circuit that is powered by a 1.5 Vbattery and connected in series by a 3.0 2 resistor and a5.0 2 resistor?A. 7.5 AB. 12.0 AC. 5.3 AD. 0.19 A

Answer 1

We will use the formula of the law of Ohm

$V=RI$

where V is the voltage, R the resistance, I is the current

in our case

V=1.5V

Because the resistors are in serie

R = 3+5= 8 ohms

we substitute the values

$I=\frac{1.5}{8}=0.1875=0.19A$

therefore the answer is D.
