The power requirement of an electronic portable device is 1. 5amp at 12 volts. What is the minimum number of aa size batteries required for powering this device? assume one aa battery is capable of supplying up to 1. 5 v and 1 amp of current. Draw a picture of your answer. (hint: how should these batteries be connected? series? parallel? both?) (4 points).

Sagot :

The battery arrangement is such that the product of the cumulative

current and voltage supplies the power requirement of the device.

Responses:

  • The minimum number of batteries (connected in series)for powering the device is 12 batteries.
  • Please find attached the drawing of the series battery arrangement

Which method of arrangement of batteries can be used to power the device?

Given:

Power requirement of the electronic device = 1.5 amp at 12 volts

Power in one AA battery = 1.5 V and 1 amp

Power, P  = Current, I × Volt, V

Therefore;

Power of the portable device, P = I.5 amp × 12 V = 18 Watt

In series, the voltage is given by the sum of the individual voltages

The current of batter arranged is series = The current of each battery

Therefore;

Voltage of 1 amp batteries required to power the 18 watt device = [tex]\dfrac{18 \, Watt}{1 \, amp}[/tex] = 18 Volts

The number of batter required to give a voltage of 18 Volt is [tex]\dfrac{18}{1.5}[/tex] = 12

Therefore;

  • 12 batteries would be required in series to power the portable electronic device

Please find attached the drawing of the batteries connected in series created with MS Visio.
