Question
4. Explain how the current in a circuit is related to the resistance in circuit. (Lesson 4)
Answers
GPT 3.5
The current in a circuit is directly related to the resistance in the circuit by Ohm's Law, which states that the current (I) flowing through a conductor is directly proportional to the voltage (V) applied across it and inversely proportional to the resistance (R) of the conductor. Mathematically, this relationship can be expressed as:
I = V / R
This means that as the resistance in a circuit increases, the current flowing through the circuit decreases, assuming the voltage remains constant. Similarly, if the resistance in a circuit decreases, the current flowing through the circuit increases. This relationship allows for the control and manipulation of current in a circuit by adjusting the resistance, which can be useful in various applications such as controlling the brightness of a light bulb or the speed of a motor.
