Question
The circuit below has two resistors. What is the current of the circuit?
R1 = 1 ohm, R2 = 4 ohms, Emf = 5 volts
![The diagram illustrates a parallel resistor circuit. It consists of two resistors, \( R_1 \) and \( R_2 \), connected in parallel. These resistors are connected to a power source, depicted as a cell on the left side of the circuit. The current from the power source splits and flows through each resistor before rejoining at the other side.
In a parallel circuit, the voltage across each resistor is the same, and the total current is the sum of the currents through each component. The equivalent resistance \( R_{\text{eq}} \) can be calculated using the formula:
\[
\frac{1}{R_{\text{eq}}} = \frac{1}{R_1} + \frac{1}{R_2}
\]
This configuration is useful for distributing the electrical current across multiple paths, often used to ensure that devices receive the same voltage from a power supply.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fb7a0f16e-a02b-440e-96fc-e97d2fe480e0%2F8e7b3e42-4331-41ef-9102-04ca16e838de%2F2m5kyko_processed.png&w=3840&q=75)
