A resistor R is connected to a voltage source VS having an internal resistance RS. A voltmeter of resistance Rm is connected across the terminals of the resistor R. The voltmeter will read a voltage of
A. $$\frac{{{V_s}{R_m}}}{{{R_s}R + {R_s}{R_m} + R{R_m}}}$$
B. $$\frac{{{V_s}R}}{{R + {R_s}}}$$
C. $$\frac{{{V_s}{R_m}}}{{R{R_s} + {R_m}}}$$
D. $$\frac{{{V_s}R{R_m}}}{{{R_s}R + {R_s}{R_m} + R{R_m}}}$$
