Reverse Resistance (RR) The value of reverse resistance is very large as compared to forward resistance. The ratio of reverse to forward resistance is 1 00 000 : 1 for silicon diodes, whereas it is 40 000 : 1 for germanium diode.
Q. What is the formula for dynamic resistance?
The diode has the following characteristics: threshold voltage V0 = 0.6 V, forward dynamic resistance Rd = 0 and infinite reverse resistance.

Q. How do you calculate dynamic resistance on a graph?
The slope of the graph between current and voltage in a p-n junction diode, under both forward bias and under reverse bias, varies a lot on varying the voltage. Hence, given the graph, how do we decide which two points to take to calculate ΔV and ΔI in order to find r=ΔV/ΔI?
Q. How do you calculate junction resistance?
The resistance of junction diode varies with applied voltage. in such cases, it is useful to define a quantity called dynamic resistance of the diode. It is the ratio of small change in applied voltage ΔV to the corresponding change in current ΔI. It is given by Rd = ΔV/ΔI.
Q. Does a diode have resistance?
Just like a resistor or any other load in a circuit, a diode offers resistance in a circuit. Unlike resistors, though, diodes are not linear devices. This means that the resistance of diodes does not vary directly and proportional to the amount of voltage and current applied to them. It changes parabolically.
Q. How do I find the equation of two points?
Steps to find the equation of a line from two points:
- Find the slope using the slope formula.
- Use the slope and one of the points to solve for the y-intercept (b).
- Once you know the value for m and the value for b, you can plug these into the slope-intercept form of a line (y = mx + b) to get the equation for the line.
Q. How do you find the equation of a line with two coordinates?
The straight line through two points will have an equation in the form y = m x + c . We can find the value of , the gradient of the line, by forming a right-angled triangle using the coordinates of the two points.
Q. What is the formula of a line?
The equation of a line is typically written as y=mx+b where m is the slope and b is the y-intercept.
Q. Do parallel lines have same equation?
Explanation: Parallel lines have the same slope and differing y-intercepts. Since /displaystyle y = 9x + 5 is the only equation with the same slope, and the y-intercept is different, this is the equation of the parallel line.
Q. How do you know if an equation is perpendicular to a line?
Explanation: Two lines are perpendicular if and only if their slopes are negative reciprocals. To find the slope, we must put the equation into slope-intercept form, , where equals the slope of the line.
