What is the voltage across a 6 Ω resistor when 3A of current passes through it?
Question
What is the voltage across a 6 Ω resistor when 3A of current passes through it?
Solution
To find the voltage across the resistor, we can use Ohm's Law, which states that the voltage (V) across a resistor is equal to the current (I) passing through it times its resistance (R). Mathematically, this is expressed as:
V = I * R
Given in the problem, we have:
I = 3A (current) R = 6Ω (resistance)
Substituting these values into the equation, we get:
V = 3A * 6Ω = 18V
So, the voltage across the 6 Ω resistor when 3A of current passes through it is 18 volts.
