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?

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.

answer in ohms and amps

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 ...continues
