An open circuit is a break in a circuit. This can be done purposely by an electronic switching component, or it could be a circuit fault caused by a bad connector or burnt-out component. This break will cause the current to stop flowing to all components fed from that point. Calculate V_{\mathrm{out}} in Figure F–7.
Because I = 0 A,
V_{2{\mathrm{k}}\Omega}=0\,\mathrm{A}\times2\,\mathrm{k}\Omega\,=\,0\,\mathrm{V}
V_{\mathrm{out}} = V_{2{\mathrm{k}}\Omega}=0\,\mathrm{V}
