How does a calculator use electric current?

Question

If so, can you also add a circuit diagram to show how it works? Please and Thank-You.

Answer 1

The liquid crystal display uses a milliwatt or so to change the orientation of the liquid crystal when the numbers are displayed. The transistors in the microchip that does the calculations use a few microwatts when they're turned on and off. Basically the calculations consist of transistors being turned on and off. When a number is stored or erased in the memory a fraction of a microwatt of electric power is needed.

Answer 2

metals have loose electrons, which can move through the wire. therefore the electrons are responsible. in a solution, for electrolysis, it will have positive and negative ions. the negative ions move to the positive terminal, looses electrons and gets deposited there, and positive ions go to negative terminal, gains electrons and get deposited there. hence in result a electron flows from negative to positive terminal of the battery. current is charge per unit time. 3 min = 180 sec. therefore total charge i 1.2*180 = 216 coloumbs and current = (3.8 x 10^-3/120) amperes

Answer 3

They are composed of hundred of on and off switches. they are grouped in a math of binary , octal or digital. but in reality all take place in binary. the no. is added or multiplied and converted to digital read out.
