1. Direct Coupled Amplifier DC Voltmeter DC Voltmeter This type of voltmeter is very common because of its low cost. This instrument can be used only to measure voltages of the order of milli-volts owing to limited amplifier gain. The circuit diagram for a direct coupled amplifier dc vo...
Voltmeter:A voltmeter is used to measure voltage. It's represented by a letter V in a circle. Motor:A transducer converts electrical energy to kinetic energy. It's represented by a letter M in a circle. Lamp:A transducer which converts electrical energy to light. ...
Voltmeters, charge symbols, waves and more When creating a circuit diagram, it’s important to understand how common electrical engineering symbols are used and what they mean. Check out our guide to circuit symbols in Lucidchart to get a head start. ...
From the circuit diagram shown find the voltmeter reading and the ammeter reading. DC Circuits: Resistors in series add up to give a total equivalent resistance. For resistors in parallel the sum of the reciprocal of the resistances equals the reciprocal of the total equivalen...

The specified Q is not the definite Q, as the losses of the voltmeter, inserted resistance & resonating capacitor are all incorporated in the circuit. Here, the definite ‘Q’ of the calculated coil is a bit larger than the specified Q. This dissimilarity is insignificant except wherever the...
Now, the voltage of the generator can be made identical to the voltage supply through regulating the shunt field resistance which is allied across the generator. This equality of generator’s two voltages & its supply can be specified with the help of the voltmeter because it provides a zero ...

Hint: think in terms of the input resistances of voltmeters and ammeters. Which of these test instrument types are known for having very large input resistance values? Which of these test instrument types are known for having very small input resistance values?
The given circuit consists of a bridge rectifier arrangement whose unregulated DC output is given to an electrolyte capacitor through a current limiting resistor. The voltage across the capacitor is monitored using a voltmeter and keeps on increasing as the capacitor charges until the voltage limit ...
