Ammeter Should Have Resistance at Abigail Lester blog

Ammeter Should Have Resistance. An ammeter with a resistance of 1 ω is to be used to measure the current supplied to a 4 ω resistor from a 100 v source. Calculate the value of shunt resistance required to convert the pmmc meter into a dc ammeter with a range of 0 to 5 amperes. I understand why voltmeters are connected in parallel and ammeters are connected in series, but why is it that to measure voltage, you must have high resistance, and to measure current, you must have. A voltmeter is placed in parallel with the voltage source to receive full voltage and must have a large resistance to limit its effect on the circuit. Rg = 100ω, ig = 3ma and. As i understand, ideally an ammeter will have zero resistance as it is connected in series with the circuit and so there will be no potential. A typical inexpensive ammeter gives a full scale deflection (fsd) when a current of 15 ma = 0.015 a flows through it. Calculate the current through the resistor before the ammeter is connected and after it is included in the circuit. Their readout is this calculated resistance. It can be adapted to measure higher currents by connecting a small resistance. An ammeter is placed in series to get the full current flowing through a branch and must have a small resistance to limit its effect on the circuit. Most common ohmmeters apply a voltage to a resistance, measure the current, and calculate the resistance using ohm ‘s law.
