STATEMENT-2: An ammeter is connected in series and a voltmeter is connected in parallel, in a circuit. AStatement-1 is True , Statement-2 is True , Statement-2 is a correct explanation for Statement-1. BStatemen
Why is an ammeter always connected in series in a circuit? What change do you observe in the reading of an ammeter if it is connected in parallel in a circuit? View Solution In an electric circuit ammeter is always connected in ___ . View Solution...
Placement of the shunt resistor in the circuit is important. If the external circuit shares a common ground with the computer containing the ammeter/data acquisition board, then you should place the shunt resistor as close to the ground leg of the circuit as possible. If not, the common-mode...
Explain the role of the internal resistance of an ammeter, and why it is necessary to connect it in series with the circuit elements. (The series current is the same.) What is the difference between series and parallel circuits? Specify in words and algebraic formula, if poss...
If you want to increase the capacity of your battery pack, you need to consider putting the battery cells in parallel. In this case, when you put batteries in parallel, the voltage will stay the same, but the capacity will add up. So, in theory, you could build a battery pack with ...
In ordinary life, we often get examples of serial and parallel connections. Suppose we have several light bulbs and a battery, then we can connect them in two possible ways. If we connect them one after the other they would be linked in a serial way, but if one of the bulbs connected...
The most common way to measure current is to connect the ammeter (a meter to measure current) or shunt resistor in series with the circuit. An ammeter or ammeter shunt is really nothing more than a highly accurate resistor. When we place a precision resistor across a circuit, a voltage dro...
Checking alternator output using an ammeter in series with the charging system should be done only by an auto-electrician. A safe test can be made with an induction ammeter held parallel to the output cable, but it is less reliable. Testing drive belt tension Check drive-belt tension on th...
If the DMM has manual ranging only, select the highest voltage range so as not to overload the input. Touch the probe tips to the circuit across a load or power source (this places the DMM sensors in parallel to the circuit being tested). View the reading in Volts, being sure to note...
The remaining resistors, capacitor, and milliammeter can be junk box items. The diode is non-critical, a 1N914 / 1N4148 type should be fine. A 1N34 would be better in theory, but most any small signal diode should work. 1N914 datasheet If you want to use this with higher power, ...
