Get started for freeIn the circuit of Fig. E25.30, the 5.0 Ω resistor is removed and replaced by a resistor of unknown resistance R. When this is done, an ideal voltmeter connected across the points band creads 1.9 V. Find (a) the current in the circuit and (b) the resistance R. (c) Graph the potential rises and drops in this circuit (see Fig. 25.20).
The circuit shown in Fig. E25.33 contains two batteries, each with an emf and an internal resistance, and two resistors. Find (a) the current in the circuit (magnitude and direction) and (b) the terminal voltage Vabof the 16.0-V battery.

A heart defibrillator is used to enable the heart to start beating if it has stopped. This is done by passing a large current ofthrough the body atfor a very short time, usuallyabout . (a) What power does the defibrillator deliver to the body, and (b) how much energy is transferred ?
Abulb is connected across the terminals of abattery havingof internal resistance. What percentage of the power of the battery is dissipated across the internal resistance and hence is not available to the bulb?
An alpha particle (a He nucleus containing two protons and two neutrons and having a mass of ) travelling horizontally at enter a uniform, vertical, magnetic field.(a) What is the diameter of the path followed by this alpha particle? (b) what effect does the magnetic field have on the speed of the particle? (c) What are the magnitude and direction of the acceleration of the alpha particle while it is in the magnetic field? (d) explain why the speed of the particle does not change even though an unbalanced external force acts on it.
