What potential difference is needed to make a current of 5 A flow through a material with resistance of 2 ohms?
Question
What potential difference is needed to make a current of 5 A flow through a material with resistance of 2 ohms?
Solution
To find the potential difference, we can use Ohm's Law, which states that the current through a conductor between two points is directly proportional to the voltage across the two points. The formula is:
V = I * R
where: V is the potential difference (voltage), I is the current, and R is the resistance.
Given in the problem: I = 5 A (amperes) R = 2 Ω (ohms)
Substitute these values into the formula:
V = 5 A * 2 Ω = 10 V
So, the potential difference needed to make a current of 5 A flow through a material with resistance of 2 ohms is 10 volts.
