A voltmeter has an internal resistance of 10 000 Ω and is used to measure the voltage across a 47.0-Ω resistor that, without the voltmeter connected, has a current of 1.20 A pass through it. How much current is drawn away from the circuit by the voltmeter when it is connected across the resistor? a. 4.7 mA b. 5.6 mA c. 1.205 A d. 0 A

b. 5.6 mA

Explanation:

As the voltmeter is connected to the resistor in parallel. The new resistance of the systems is

R = 1/0.0214 = 46.78 Ω

The voltage is

So the new current now of the system is

So about 1.2056 - 1.2 = 0.0056 A or 5.6mA is drawn away.

answer: pseudoscience

false
