Question

A current flows through a 6
resistor and the potential
difference across the resistor is
15V. What current flows through
the resistor? (don't use any units,
numbers only)

Answer 1

Answer:

2.5 A

Explanation:

Ohms law is a physical law relating the voltage difference between two points, the electric current flowing between them, and the resistance of the path of the current. Mathematically, the law states that V = IR, where V is the voltage difference, I is the current in amperes, and R is the resistance in ohms. It is can easily be deduced from the foregoing that the voltage is directly proportional to current and the resistance is the constant of proportionality.

From ohm's law;

R= 6Ω

V= 15V

I= ???

V=IR

I= V/R

I= 15 V/6Ω

I= 2.5 A
