To check if the connections in the circuit are correct, the galvanometer deflections must be in the opposite direction. This is done by inserting the key K1and making the note of the ammeter reading. To get the null point on the fourth wire, the rheostat should be adju...
1. Mesh or loop (closed-circuit portion consisting of a single cable and the devices it connects) 2. Nodes (points of the circuit where 2 or more cables are joined) 3. Branches (portion of circuit formed by a single cable that is between two consecutive nodes) ...
For example, an analogvoltmeterwith a ±3% accuracy is set to the 0 to 100-V range. Based on this accuracy, its pointer can be 3 volts (100 V x 0.03 = 3 V) below or above the true reading. If the true measured value is, for example, 90.0 V, the meter might read between 87 ...
- Needed no matter what: a reliable digital voltmeter (DVM); 8mm and 10mm sockets; small torque wrench for re-tightening 8mm nuts. Getting the torque wrong can be quite costly. I have a junky 1/8" Harbor Freight one. It works. - Needed if you likely have one or more bad modules an...
V and 93 V or ± 3.3% of reading. However, 10.0 volts measured on a 100-V scale of the same voltmeter can read between 7 V and 13 V, or ± 30% of the actual reading, while the meter is technically within specifications. So, to maintain reasonable accuracy, select the analog meter...
