Let the given voltmeter is ideal so that resistance of voltmeter is infinity.
Now by applying the Voltage division rule in the circuit diagram given in the question.
\(V_1=\frac{R_1}{R_1+R_2}\times V\)
\(V_2=\frac{R_2}{R_1+R_2}\times V\)
V1 = voltage across R1 resistance
V2 = voltage across R2 reistance
V = Total voltage
Calculation:
Given: V = 5 V
So, voltage across 1kΩ is,
\(V_1=\frac{R_1}{R_1+R_2}\times V\)
\(V_2=~\frac{1}{1\; +\; 4}\times5=1~V\)
