You might have paid more attention to the charging system gauge or warning light afterward. The amount of electrical current that the charging system provides to your vehicle's battery is monitored by either a voltmeter, which measures the voltage in the charging system, or an ammeter, which ...
Next, remove the covers on the battery terminals. Connect the positive point of the voltmeter to the red battery terminal, while the negative point should be connected to the black battery terminal. Check the readings; a good battery should indicate a voltage between 12.4 V and 12.7 V. A re...
You mentioned that you used the same meter to measure the current. The Current range of a digital ammeter has some low, non-zero, internal resistance, which would add to your effective load resistance. Has this been taken into account?
Voltage can be measured by using a voltmeter. Current can be measured by using an ammeter. In a parallel circuit, the magnitude of voltage remains the same. In a series circuit, the magnitude of the current remains the same. The voltage creates a magnetic field around it. The current creat...
d. Connect the circuit; (2) Operation Adjust the sliding rheostat, read the ammeter and voltmeter in turn, and record the table. (3) Data processing Method A. Calculate each resistance by mathematical calculation and then calculate the average value to get the resistance value. Method B. By...
