Question

Ohm's law states that

• A. Current is directly proportional to resistance
• B. Current is directly proportional to voltage
• C. Current is inversely proportional to voltage
• D. Resistance is directly proportional to current

Hint:

Ohm's law is \(V=IR\). For constant resistance, current is directly proportional to voltage.

Answer 1

The Correct Option is B

Concept: Ohm's law gives the relationship between voltage, current, and resistance in an electrical circuit.

Step 1: According to Ohm's law: \[ V=IR \] where: \[ V=\text{Voltage},\quad I=\text{Current},\quad R=\text{Resistance} \]

Step 2: If resistance \(R\) remains constant, then: \[ V\propto I \] This means: \[ I\propto V \]

Step 3: Therefore, current is directly proportional to voltage, provided temperature and other physical conditions remain constant. Hence, the correct statement is: \[ \boxed{\text{Current is directly proportional to voltage}} \]
