Question

Three 5 Ohm resistors are connected in parallel to a 9 Volt power supply. What is the current through each resistor?

Answer 1

I₁ = I₂ = I₃ = 12 A

Step-by-step explanation:

Since the resistors are connected in parallel across a battery. Hence, the voltage across each of them will be the same, which will be equal to the voltage of the power supply. Since each resistor has the same resistance of 5 Ω. Therefore. the current across each resistor will also be the same. We can easily calculate these current values by the use of Ohm's Law, as follows:

`V = IR\\I_(1)=I_(2)=I_(3)=(V)/(R) \\\\I_(1)=I_(2)=I_(3)=(9\ Volt)/(5 \Omega)\\\\`

I₁ = I₂ = I₃ = 12 A
