An ammeter is a device that is used to measure current by connecting it in series – and never in parallel – in an electrical circuit. (A parallel circuit has multiple wires between junctions – in other words, at the power source, capacitors and resistors – in the circuit.) It operates...
First starts better to make with powering the circuit through some variac. It helps to control the power if something tries to go wrong. It is also wise to connect an ammeter (rated to 10 amps) in series with the circuit. Don't use those fancy electronic ammeters - they will show erro...
redraw your circuit from part ( a ) with an ammeter included in a config - uration that will allow the ammeter to measure the current flowing through bulb 2 . use the appropriate schematic symbol for an ideal ammeter. ( d ) redr...
a Printed Circuit Board (PCB) and a 9v battery. This project was designed to be mounted on a PCB, however you don’t have to. You could construct the project on Vero board (strip board) or any other 0.1” pitch style of project board. If you just want to experiment with this ...

The MOSFET has reverse high power diode that is used to charge the battery there is no need to add a special diode to the circuit. I've shown the switching principle with relays in the schematic. RL3 must be used with a cutt off circuit. ...
This second simple capacitance meter circuit provides 14 linearly calibrated capacitance measuring ranges, from 5 pF to 15 uF FSD. S1 is employed as a range switch, and operates in collaboration with S4 (s1/x10) and S3 (x l) or S2 (x3). The IC 7413 operates like an astable oscillator,...
Electronic Thermometer Circuit Diagram Here another Operational amplifier is used as a voltage amplifier. The output from IC1 is amplified by the operational amplifier IC2. The ammeter indicates the current amplitude of the output signal and this is calibrated to indicate the value of the temperature...
