Question

There are 4 different sized charge carrying balls (A, B, C and D) floating in space. If we probe an ideal voltmeter between ball A and B it shows 10V, If we probe ideal voltmeter between ball C and D it shows 50V. What voltage will it show if we probe ideal voltmeter between ball B and C? Why? (refer to figure?​

Answer 1

Answer:

Explanation:

The internal resistance of an ideal current source is infinite. An independent current source with zero current is identical to an ideal open circuit. The voltage across an ideal current source is completely determined by the circuit it is connected to.
