Question

What does Ohm law teach about current and resistance

Answer 1

Directly proportional to voltage but inversely proportional to resistance

Step-by-step explanation:

The law mentions that current is directly proportional to voltage but inversely proportional to resistance. At constant resistance, current increases as voltage increases and vice versa. At a constant voltage, the current decreases as resistance increases and vice versa.

Answer 2

Ohm's Law states that the current through a conductor between two points is directly proportional to the voltage across the two points, and inversely proportional to the resistance between them. Mathematically, this can be expressed as:

I = V/R

Where:

I is the current flowing through the conductor in amperes (A)

V is the voltage across the two points in volts (V)

R is the resistance between the two points in ohms (Ω)

This equation shows that if the voltage (V) is increased while the resistance (R) stays constant, the current (I) will also increase. Conversely, if the resistance (R) is increased while the voltage (V) stays constant, the current (I) will decrease.

This relationship is fundamental to the behavior of electric circuits, and is used extensively in circuit analysis and design.
