Before connecting the voltmeter, potential difference across $$100$$  Ω$$Vi=100100+10$$  ×  $$V=1011$$ VFinally after connecting voltmeter across $$100$$  ΩEquivalent resistance $$100$$ × $$900100+900$$  $$90$$  ΩFinal potential difference,$$Vf=$$ $$9090+10$$ × $$V=910$$ V %  error $$=Vi$$ −VfVi  ×  $$100=1011$$  V  −  $$910$$ $$V1011$$  V ×  $$100$$ $$=$$  $$1.0$$ %
