Why The Resistance Of Voltmeter Should Be High at Brandi Stevens blog

Why The Resistance Of Voltmeter Should Be High. Vacuum tube voltmeters (vtvms), transistor. An ideal voltmeter has infinite resistance. Why should a voltmeter have a higher resistance than of any circuit element across which the voltmeter is connected? Your reasoning is correct if you take “voltmeter” to mean galvanometer (a device which deflects a needle using a coil in a. This is because a voltmeter is connected in parallel i n a circuit across resistor/resistors. The resistance of an ideal voltmeter should be infinite. Most common ohmmeters apply a voltage to a resistance, measure the current, and calculate the resistance using ohm ‘s law. Too low of internal resistance in a voltmeter will adversely affect the circuit being measured. If a voltmeter has a high internal resistance, it will draw less current from the circuit being measured. Their readout is this calculated resistance. Now, if the voltmeter has low. A voltmeter should have a much larger resistance compared to any circuit element across which it is connected because a low internal resistance. As we know, v=i*r, i.e., voltage across a resistor equals the product of its resistance and current flowing through it.

The voltmeter reads 40 V across 60 Omega resistance. The resistance of
