Questions and Exercises Choose yes or no in the answers to the following questions. (a) To measure the resistance of a resistor in a circuit you need to break the circuit, i.e., pull out a leg (b) To measure the voltage across a resistor in a circuit you need to break the circuit, i.e., pull out a (c) To measure the current through a resistor in a circuit you need to break the circuit, i.e., pull out a of the resistor from the circuit. Answer: Yes(), No ). leg of the resistor from the circuit. Answer: Yes ), No () leg of the resistor from the circuit. Answer: Yes (), No ().

Explanation / Answer

(A) Yes.

You do need to break the circuit. This is because if the circuit is left complete, your "experienced" resistance across the leads (legs as you would call it) will not just be the resistor, but it will see all other components as resistive elements in parallel. Even components like capacitors, inductors, and sources all have actual resistances to them in real circuits, and they will act as such.

(b) No.

(c) Yes.
