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 <u>12 batteries</u>.
- Please find attached the drawing of the series battery arrangement
<h3>Which method of arrangement of batteries can be used to power the device?</h3>
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 =
= 18 Volts
The number of batter required to give a voltage of 18 Volt is
= 12
Therefore;
- <u>12 batteries would be required in series to power the portable electronic device</u>
