A 60.0 ohm resistor is connected in parallel with a 115.0 ohm resistor. This parallel group is connected in series with a 15.0hm resistor. The total combination is connected across a 15.0-V battery. Find the current and power in the 115 ohm resistor.

Equivalent Capacitance

Evaluate the equivalent capacitance in the attached file 'Capacitor.doc'. All the capacitors are identical and each has a capacitance of C.

In a heart pacemaker, a pulse is delivered to the heart 81 times per minute. The capacitor that controls this pulsing rate discharges through a resistance of 1.8e6 ohms . One pulse is delivered every time the fully charged capacitor loses 62.9 % of its original charge. What is the capacitance of the capacitor?

answer in ohms

A 1.40 ohm resistor is connected across a 9.00-V battery. The voltage between the terminals of the battery is observed to be only 8.00 V. Find the internal resistance of the battery.

The total current delivered to a number of devices connected in parallel is the sum of the individual currents in each device. Circuit breakers are resettable automatic switches that protect against a dangerously large total current by "opening" to stop the current at a specified safe value. A 1500 W toaster, a 1030 W iron, and a 1000 W microwave oven are turned on in a kitchen. As the drawing shows, they are all connected through a 20 A circuit breaker to an ac voltage of 120 V.Find the equivalent resistance of the three devices and the total current delivered by the source.
