Question

Two resistor each of value 8AOhm and 10 ohm are connected in parallel to a cell of 3 volt .find the total current draw from the cell.

Answer 1

Effective reisitance = r1r2/r1 +r2

10×8 / 10+8

80/18

40/9 isR effective

V =3

I=?

By ohms law V =IR

I =R/V

I = 40/9/3

I= 40/9× 1/3

I=40 /27 ampere
