In 5V circuit has two 2 Ohm resistors in parallel, what is the current passing through each resistor?

To solve this question we need to remember the equation "Voltage = Current x Resistance". The next step is to draw out the circuit. A 5V circuit means the battery is supplying 5V to the current. Two 2 Ohm resistors in parallel means the resistors are stacked on top of each other in the circuit rather than next to each other (that is called a series circuit). When thinking about current, you can imagine a flow of water. When the flow has two options of a path to take, it will split up. This means the current flowing throw each resistor will be less than the total current in the circuit. Remember this when checking your answer. 'Voltage = Current x Resistance' therefore 'Current = Voltage / Resistance'. So th current passing through one resistor would be '5/2=2.5' so 2.5 A. The value of both resistors is the same so 2.5A would pass through both resistors.
