WebHere V is constant (220V) I=V/P (ohm's law) P= (V^2)/R. (so far the same as @Prithvi Sriram mentioned, but here's the shortcut) if v is constant v^2 will also be constant. P is inversely proportional to R. if P increases, R decreases. that is why the 2nd bulb offers more resistance. remember---only if V is constant. WebForward Voltage (VF) Except in special cases, changes in VF are caused by variations in the emission wavelength and semiconductor bandgap. When the temperature rises VF …

Does forward current of diode has any affect on forward voltage?
Webincrease in current causes a slight increase in resistance, since most of the excess heat is dissipated. At point C, overcurrent causes heat buildup. The PTC fuse enters a state of high resistance at Point D, after Point C, and limits current flow. (Current flow produces heat at a rate proportional to I2R.) Since PTC resettable fuses are thermally WebIdeal Diodes. The key function of an ideal diode is to control the direction of current-flow. Current passing through a diode can only go in one direction, called the forward direction. Current trying to flow the reverse direction is blocked.
