Meter loading Work this problem to five-digit precision. Refer to Figure P28.44.
(a) When a 180.00- Ω resistor is connected across a battery of emf 6.000 0 V and internal resistance 20.000 ', what is the current in the resistor? What is the potential difference across it?
(b) Suppose now an ammeter of resistance 0.50000 Ω and a voltmeter of resistance 20 000 Ω are added to the circuit as shown in Figure P28.44b. Find the reading of each.
(c) What If? Now one terminal of one wire is moved, as shown in Figure P28.44c. Find the new meter readings.
