1. Battery:Definition: A source of energy. It contains active materials which are irreversibly converted during the chemical reaction.In physics, one "battery" on its own is called a cell. Two or more cells which are joined together are called a battery.
Symbol:
Uses and Function: Batteries can be used for several functions:? Storage: Batteries store energy being produced by a given generating source, and when this source
is unavailable this energy can be used by the load? Start- up current: Batteries can provide higher currents to the load than the array alone can
provide. Many motors initially have a high current requirement.? Power conditioning: Two cases where this feature is used in directly coupled systems, such as
water pumping, and in uninterruptable power supplies.

12Time-delay electric fan
8-72-12, 40-71, 14-39, 16-11, 6-13, 38-58, 7-48, 5-15-57-47
Complete all wiring connections as indicated in the sequence. After switching ON for a time period, the fan will start to spin. This delay is due to the charging of the capacitor. During the charging, the base electrode of the triode is in a low voltage so that the triode is shut. When the capacitor is charged fully, the triode is in its conducting condition, thus the fan will spin. The time-delay period is the duration of the charging.
NOTE: Every time when you perform this experiment once, remember to “discharge” the capacitor before doing it again. Otherwise it won’t work properly. To “discharge”, connect any wire to 57-58 for a second. This way the electricity stored in the capacitor will be “discharged” and then the experiment can work properly again.

Adjust the variable resistor from minimum to maximum, the meter pointer will also change from minimum to maximum, and the output voltage will also change from minimum to maximum. At this time, the voltage indicated by the meter is the output voltage. This indicates the voltage that will be provided when connecting a device to VOUT+ and VOUT-. You can just assume VOUT+ and VOUT- are +ve and –ve poles of a battery which is a source of electricity power. For example, adjust the variable resistor so that the reading of the meter is 3V. Then connect the motor to VOUT+ and VOUT- . At this time, there will be a 3V current pass through the motor to make it work. In practice, this circuitry can be adjusted per desired voltage. It is easy and practical.
