Determine and plot the average power delivered to a 100-Ω load in place of the light bulb in Example as a function of resistor R. (When the SCR is on you can write an equation for the instantaneous power across the load. The average is found by integrating the instantaneous power over one period.)
Example
An SCR with a 4.0-V trigger is used in the circuit of Figure as a light-dimmer control. What resistance, R, should be used to provide approximately 10% to 90% on time?
