WebIn effect, an alternating current can flow 'through' a capacitor, whereas a direct current cannot. Phase difference between V and I If the p.d. applied to the capacitor is given by: Notice that I has its maximum value ¼ cycle before V has its maximum value. We say that the current leads the voltage by ¼ cycle. WebIn direct current (DC), the electric charge (current) only flows in one direction. Electric charge in alternating current (AC), on the other hand, changes direction periodically. The voltage in AC circuits also periodically reverses because the current changes direction. Most of the digital electronics that you build will use DC. WebIt works on the principle that the length of the wire increases because of the heating effect of the current flow through it The hot wire instrument is used for both the AC and DC current. EXPLANATION: When the current is passed through the fine platinum-iridium wire it gets heated up and expands. fire rated wood houston
