## Question:

Consider the circuit shown in the following figure. The current through the R1 = 7.00-{eq}\Omega {/eq} resistor is 4.30 A, in the direction shown. What are the currents through the 25.0-{eq}\Omega {/eq} and 20.0- {eq}\Omega {/eq} resistors?

## Electric current

Electric current is the rate of flow of electric charge (which is often carried by electrons moving in a wire or in ionized gas such as plasma or ions in an electrolyte) in a given point or region. It is usually denoted as {eq}I{/eq} and the unit is amperes. In conductors, these moving charges are called charge carriers.

## Answer and Explanation:

Since there is no picture present, we determine the current that runs through each resistors both when they are connected in series and in parallel.

a. In series circuits

There is only one path for the current to flow, therefore, the current that runs through each resistor is the same.

b. In parallel circuits

There are multiple paths for the current to pass through, therefore, each of the resistor will have varying currents. Since there is no given for the voltage, the {eq}25\Omega{/eq} resistor have the lowest current, followed by the {eq}20\Omega{/eq} and then lastly, the {eq}7\Omega{/eq} resistor will have the largest current.
