Chapter 6, Problem 44R

To determine

To Choose: The correct option.

Explanation of Solution

Introduction:

There exists a relation between voltage difference, current, and resistance in a circuit.

The relationship betweencurrent, voltage difference and resistance in a circuit is given by Ohm’s law.

According to this law, voltage difference across a circuit is directly proportional to the current and resistance in the circuit

It can be expressed as the following equation:

V=IR

Where I is the current in a circuit in amperes, V is the voltage difference across the circuit in volts and R is the resistance of the circuit in ohms.

Conclusion: Option B. correctly expresses the relationship between voltage, current and resistance.
