The measured voltage around the 47 Ω resistor is 0.386 V. Please see the set-up below.
So we can count on our calculation, we will always find these small differences between the
calculations and the real measurements because of the tolerance of the components.
8.4 Shunt Resistor
It is a way to measure current through a bath in the circuit using a small value resistor, we cut the
circuit and connect it again using the shunt resistor. In most cases, it should be a high power resistor to
handle the current passing through it.
So depending on ohm’s law “ ”, we have a shunt resistor, and we have a current passing
𝑉 = 𝐼 · 𝑅
through it, so the voltage will be generated around it. And then we will measure this voltage using the
multimeter, this way we have converted the current into voltage.
