In the circuit seen here, the resistor has a resistance of 3 ohms. If no change in the battery size occurs, what will happen to the current if the resistance increases to 6 ohms?

Answer 1

Since only 1 resistor is mentioned, the only possibility is a series type circuit.

also V= IR. therefore current and resistance are inversely proportional.

as resistance doubles, the current will be halved in order to maintain voltage.

I hope this answers your question.
