WebThe 10K value for R7 is just a placeholder. R7 is what I'm trying to determine. The transistor should turn the relay on and off based on whether D2 is at 5V or GND. The relay is a 5V relay and has a coil resistance of 63 Ohms, so the coil current is 79.4mA. How do I determine what value the base resistor (R7) should have for the circuit to work? WebTo get this current you adjust the slope of the resistor load line until the intersection point is at the current you want. Then figure out the resistor value from the slope. The slope of the resistor load line is − 1 R -\dfrac{1}{\text R} − R 1 minus, start fraction, 1, divided by, start text, R, end text, end fraction . WebThere are many different types of adjustable resistors. The simplest are wirewound resistors with some of the wire exposed so that a movable electrode can be attached. … contract carpentry dundee il
