For the following circuit i am confused to as why Resistor R4 when measured on the breadboard is 35k ohms, when it is meant to be 47k Ohms (as it is a 47 k ohm resistor. Also when it is taken out of the circuit and measured it is fine and gives the 47k ohm as expected) . The other resistors when measured match up to what they are meant to be. I assume the reason it is giving this reading is due to the configuration it is in? Such as something to do with the voltage divider, maybe something else?
- Note for the circuit schematics i have just put 35k ohms just to see if my simulated results would match up to what the breadboard circuit outputted on an oscilloscope. It is actually meant to be 47k ohms
- Not understanding why the 47k ohm resistor (R4) reads 35k ohm on the multimeter
- How do i calculate what this resistor value will be due to the difference? As in i find what value i want, in this case i needed 47k ohm for the specified application but due to this resistor value difference, how am i meant to see what 47k will actually be. As in will i need to use a 56k or something to get the 47k due to the difference? Hence what formula am i meant to use to find what value this resistor will actually be when in theory its meant to be 47k ohms?
