Get started for freeTwo coils have mutual inductance . The current in the first coil increases at a uniform rate of 830 A/S. (a) what is the magnitude of the induced emf in the second coil? Is it constant? (b) Suppose that the current described is in the second coil rather than the first. What is the magnitude of the induced emf in the first coil?
In an L-R-C series circuit, what criteria could be used to decide whether the system is over damped or underdamped? For example, could we compare the maximum energy stored during one cycle to the energy dissipated during one cycle? Explain.
An idealized voltmeter is connected across the terminals of abattery, and arole="math" localid="1655719696009" appliance is also connected across its terminals. If the voltmeter reads (a) how much power is being dissipated by the appliance, and (b) what is the internal resistance of the battery?
In the circuit, in Fig. E26.47 the capacitors are initially uncharged, the battery has no internal resistance, and the ammeter is idealized. Find the ammeter reading (a) just after the switch S is closed and (b) after S has been closed for a very long time.
Light Bulbs in Series and in Parallel. Two light bulbs have constant resistances of and . If the two light bulbs are connected in series across a line, find (a) the current through each bulb; (b) the power dissipated in each bulb; (c) the total power dissipated in both bulbs. The two light bulbs are now connected in parallel across theline. Find (d) the current through each bulb; (e) the power dissipated in each bulb; (f) the total power dissipated in both bulbs. (g) In each situation, which of the two bulbs glows the brightest? (h) In which situation is there a greater total light output from both bulbs combined?
