What happens to current when resistance increases?
Understand the Problem
The question is asking about the relationship between current and resistance, specifically what occurs when resistance increases. This relates to Ohm's law, which states that current is inversely proportional to resistance in a circuit for a constant voltage. Hence, if resistance increases, the current decreases.
Answer
Current decreases
Current decreases when resistance increases.
Answer for screen readers
Current decreases when resistance increases.
More Information
According to Ohm's law, the current (I) in a circuit is inversely proportional to the resistance (R) when the voltage (V) is constant. This relationship is expressed mathematically as I = V/R.
Tips
A common mistake is to forget that this relationship assumes other factors, such as voltage, remain constant.
