3. No , the diode does not conduct symmetrically when the
current flows in the forward (positive voltage) and the reverse
(negative voltage) direction.
In forward bias , after a knee voltage diode behaves close to an
open switch and the current increase exponentially with the voltage
applied while in reverse bias diode conduct a very very small
current which is essentially negligible for most purposes and can
be considered as open circuit

1. The filament of a standard 100-W light bulb has a resistance of about 100 ohms. For this laboratory the glass of the light bulb is unfrosted, so that the filament can be viewed directly. The light bulb is connected to a variable AC voltage source (a Variac), which can deliver up to 140 volts AC. When the voltage is low, about 20 volts, the filament is a dull, red color. When the voltage is high, 100 V, how does...
A circuit consists of a 3-volt battery; connecting wires with very low resistivity; a light bulb with resistance = 2Ω. a. How much current is flowing through the bulb? b. How much energy per second is converted from electrical potential energy to light and heat? c. If the bulb is replaced with one with higher resistance, in what way (increase, decrease, stay the same) would voltage and current change?
Problem 3:[15]) A light bulb is connected in the circuit shown in the figure with the switch S open. All the connecting leads have no appreciable resistance and the battery has no internal resistance. All resistances including the bulb have R=20 Ohms and the battery voltage is 1do Volts. (a) When the switch S is open and when it is closed, what are the effective resistances of the circuit in both cases? [5] (b) When the switch is open and...
Light bulb A is marked "25 W 120 V" and light bulb B "100 W 120 V"; this means that each bulb converts its respective power when plugged into a constant 120 V source, Find the resistance of each bulb, How long does it take for 1.00 C to pass into bulb A?

Review Con: Part A An incandescent light bulb uses a coiled filament of tungsten that is 580 mm long with a diameter of 46.0 um. At 20.0°C tungsten has a resistivity of 5.25 x 1012.m. Its temperature coefficient of resistivity is 0.0045 (Cº) , and this remains accurate even at high temperatures. The temperature of the filament increases linearly with current, from 20°C when no current flows to 2520°C at 1.00 A of current What is the resistance of the...
