Connecting an ammeter in a circuit can be done either before or after the load without affecting the current, as the current remains constant throughout the circuit. However, for safety and measurement accuracy, it is recommended to position the ammeter close to ground potential. This minimizes the risk of measurement corruption due to leakage currents, especially when dealing with high potential measurements. Proper placement of instrumentation and controls is crucial for reliable readings.
PREREQUISITESElectrical engineers, technicians, and students interested in circuit design and measurement accuracy will benefit from this discussion.
This is correct. For safety reasons, it is preferred that instrumentation, switches/controls, be placed as close to ground potential as possible/convenient. Additionally, depending upon the measurements being made, there will be less corruption of the measurement by leakage currents from high potential through/around the measurement device to ground.Usama Khurram said:the current should remain same in circuit and there should be no restriction for Ammeter connection so it can be placed anywhere in the circuit
