In ammeter designs, externalresistorsadded to extend the usable range of the movement are connected inparallelwith the movement rather than inseriesas is the case for voltmeters. This is because we want to divide the measured current, not the measured voltage, going to the movement, and because...

A parallel resistor is provided, consisting of a resistor in series with two antiparallel diodes; or at least one of the parallel or series resistors consists of a resistor in series or in parallel with a controlled SC device whose control voltage is a function of the measured voltage. By ...
A voltmeter is always connected: - in parallel with the element whose potential difference is being measured. - in series with the element whose potential difference is being measured. A 4.0 \ \Omega resistor, a 7.0 \ \Om...
When a shunt (parallel) resistance of very low value is connected in parallel with a basic galvanometer, it becomes an ammeter and can be used to measure current in the circuit. The shunt resistance can calculated as follows − Refer the circuit, ...
Voltmeter and ammeter are the devices used for estimating the voltage and the current in the circuit, respectively. There are two types of voltmeter and ammeter. One is analog, and the other one is digital. The digital device has more accuracy than the analog. ...
Just like voltmeters, ammeters tend to influence the amount of current in the circuits they’re connected to. However, unlike the ideal voltmeter, the ideal ammeter has zero internal resistance, so as to drop as little voltage as possible as current flows through it. Note that this ideal ...
Given: E = 48.0 V, R1 = 24 ohms, and R2 = 96 ohms. a) Find I_1, I_2 and I_3 in the circuit below. b) Find the voltage on R_1, R_2 and R_3. c) Find the power of R_1, R:2 and R_3. Suppose the series resistors are 2.00 ohms and 4.00 ohms while the ...
