Given a 10 V power supply would a 20 ohm resistor in a 5 ohm resistor need to be arranged in parallel or series to generate a current of 2.5 a? How much current would move through each resistor?
To generate a current of 2.5 A, the resistors need to be arranged in parallel.
In a parallel circuit, the voltage across each resistor is the same, and the total current flowing through the circuit is equal to the sum of the currents flowing through each individual resistor.
To find the current flowing through each resistor, we can use Ohm's Law: I = V/R, where I is the current, V is the voltage, and R is the resistance.
For the 20 ohm resistor:
I1 = V/R1 = 10V / 20Ω = 0.5 A
For the 5 ohm resistor:
I2 = V/R2 = 10V / 5Ω = 2 A
Therefore, the current flowing through the 20 ohm resistor would be 0.5 A, and the current flowing through the 5 ohm resistor would be 2 A.
