Final answer:
The current through the battery is found using Ohm's law and depends on the total resistance in the circuit. For a parallel circuit, the total current is the sum of the currents through each branch, each calculated using the voltage of the battery and resistance of the individual branch.
Step-by-step explanation:
The current through the battery can be calculated using principles of electric circuits, specifically Ohm's law and the rules for series and parallel circuits. Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points and inversely proportional to the resistance between them. The formula for Ohm's law is I = V/R, where I is the current, V is the voltage, and R is the resistance.
In a parallel circuit, the total current supplied by the battery is the sum of the currents in each parallel branch. As mentioned, we can use Ohm's law to find the current going through each branch of this circuit. When resistors are arranged in parallel, they each receive the full voltage of the battery, so if you have a battery with a voltage V and two resistors Rblue and Rred, the current through each resistor would be I_blue = V/Rblue and I_red = V/Rred respectively. The total current supplied by the battery is then I_total = I_blue + I_red. In one of the given statements, it is implied that the total current through the battery is 1.4 A.
The rate at which charge flows, or current, is measured in amperes (A). One ampere is defined as the flow of one coulomb of charge through an area in one second. Using this knowledge, we can also answer questions such as the amount of charge flowing in a circuit over time or determining the current by knowing the charge flow and time interval.
