If the battery voltage is 20 Volts, what is the voltage drop across R2?d
19.4 V

In this circuit, the voltmeter acts like:
a very small resistor so only a tiny amount of current goes through the meter
a very large resistor so only a tiny amount of current goes through the meter
An ammeter in a circuit acts like:
very small resistor so the voltage drop is minimal across the meter
very big resistor so the voltage drop is minimal across the meter
very small resistor so the voltage drop is large across the meter
very big resistor so the voltage drop is large across the meter
In this circuit, the meter is connected correctly and will NOT impact the function of the circuit.
True
False
