Problem

A resistor

R_1 = 2\,\text{k}\Omega

is connected in series with a resistor

R_2 = 3\,\text{k}\Omega

across a

15\,\text{V}

DC supply. A load resistor

R_L = 5\,\text{k}\Omega

is connected across

R_2

. (i) Find the equivalent resistance of

R_2

and

R_L

. (ii) Determine the potential difference across the load resistor

R_L
