What happens when an ideal voltmeter (resistance Rv=infinity) and an ideal ammet

Question

What happens when an ideal voltmeter (resistance Rv=infinity) and an ideal ammeter (resistance Ra=0) are both accidentally connected in parallel with a 10 ohm resistor that was carrying a current of 5 amps? The current in the 10 ohm resistor A. Doubles B. Becomes half as much C. Become zero D. Is unchanged What happens when an ideal voltmeter (resistance Rv=infinity) and an ideal ammeter (resistance Ra=0) are both accidentally connected in parallel with a 10 ohm resistor that was carrying a current of 5 amps? The current in the 10 ohm resistor A. Doubles B. Becomes half as much C. Become zero D. Is unchanged A. Doubles B. Becomes half as much C. Become zero D. Is unchanged

Explanation / Answer

As an Ammeter has very low internal resistance therefore ammeter connected in series so that all the current flowing in the circuit element must flow through the ammeter in order for it to measure the current. So if we connect it across i.e. in parallel to any circuit element, we will be shorting that element. Because of this shorting of the element

C. Become zero
