Answer 3 Questions
- If one lamp of a group of five identical lamps in series is removed, the voltage across the empty socket becomes equal to the line voltage, rather than remaining one-fifth of it. Why?
- The circuits, P and Q, show two different ammeter-voltmeter methods of measuring resistance. Suppose the ammeter has a resistance of 0.10 ohms and the voltmeter has a resistance of 3.0 ohms; the ammeter reads 2.5 amps and the voltmeter reads 6.0 volts. What is the uncorrected value of the resistance in each case? What is the true value of the resistance in each case
- A piece of copper wire of resistance Riscut into10 equal lengths.These partsare connected in parallel. How does the joint resistance of the parallel combination compare with the original resistance of the single wire?
