Question

What is the current through a 25 ohm resistor connected to a 5.0 V power supply? a 0.20 A b 5.0 A c 25 A d 30 A

Answer 1

~Formula: Voltage= current• resistance
(V= Ir)
~Using this formula, plug in the numbers from the equation into the formula
~5=25i
~Now you have a one-step equation
~Divide by 25 on both sides and you should get your answer:
~I= 0.2 (which means current is 0.2)

Answer 2

The current through a 25 ohm resistor connected to a 5.0 V power supply is 0.2 A. Option A is correct.

Ohm's Law:

The voltage of the two points between in a conductor is directly proportional to the current flows through the conductor.

V = IR

Where,

V = voltage  = 5.0 V

I = current  = ?

R = resistance -  25  ohm

Put the values in the equation,

5 = 25 x I

I = 0.2 A

Therefore,  the current through a 25 ohm resistor connected to a 5.0 V power supply is 0.2 A.
