1\,\text{k}\Omega

sensor must be supplied with a steady

5\,\text{V}

from a

15\,\text{V}

DC source. The circuit uses two resistors:

R_1

is connected in series with

R_2 = 4\,\text{k}\Omega

; the sensor is connected in parallel with

R_2

. What value of

R_1

will ensure that the sensor receives exactly

5\,\text{V}

? (a)

2.4\,\text{k}\Omega

(b)

1.6\,\text{k}\Omega

(c)

2.0\,\text{k}\Omega

(d)

0.4\,\text{k}\Omega
