(B) In an $AC$ series $LR$ circuit,the voltage across the resistor $(V_R)$ and the inductor $(V_L)$ are out of phase by $90^{\circ}$.The total potential difference $(V)$ of the source is given by the phasor sum:$V = \sqrt{V_R^2 + V_L^2}$Given:$V_L = 16 \, V$$V_R = 20 \, V$Substituting the values:$V = \sqrt{(20)^2 + (16)^2}$$V = \sqrt{400 + 256}$$V = \sqrt{656}$$V \approx 25.61 \, V$Rounding to the nearest provided option,the total potential difference is $25.6 \, V$.
