Question: If designed properly a good ammeter should have a very
If designed properly, a good ammeter should have a very small resistance. Why? Explain clearly, using Kirchhoff’s laws.
Answer to relevant QuestionsAre the joule heating rates for resistors in series generally the same? If not, under what circumstance(s) could they be the same? Light bulbs are labeled with their power output. For example, when a lightbulb is labeled 60 W, it is assumed that the bulb is connected to a 120- V source. Suppose you have two bulbs. A60- W bulb is followed by a 40- W bulb ...For the circuit shown in Fig. 18.31, find (a) The cur-rent in each resistor, (b) The voltage across each resistor, and (c) The total power delivered. (a) Determine the equivalent resistance of the circuit in Fig. 18.34 Find (b) The current in each resistor, (c) The voltage across each resistor, and (d) The total power delivered to the circuit. For the multiloop circuit shown in Fig. 18.39, what is the current in each branch?
