Find out the reading of ammeter and voltmeter
WebApr 5, 2024 · For voltmeter reading, we have to find voltage across 12 Ω resistance; From ammeter reading, current in circuit or across 12 Ω resistance is, i = 6 25 A Since, R = V I or V = I R So for voltage across 12 Ω resistance is, V = 12 i Putting value of “i” we get, V = 12 × 6 25 V ⇒ V = 72 25 V ∴ V = 2.88 V WebThey are almost always labelled as being "True RMS" or RMS reading" or "RMS". Some meters are designed to display peak values, but these are usually for specialist purposes. Note that while many modern multimeters have a "peak hold" feature, this will display the peak displayed voltage since the peak-hold button was pressed and NOT the peak ...
