1. Question 1

   Q1. A voltage source is connected to a circuit with a variable resistance. What happens to the current?

   • A) The current increases due to the applied voltage
   • B) The current decreases due to the high resistance
   • C) The current remains the same due to the voltage source
   • D) The current is zero due to the absence of voltage

   Answer: The current decreases due to the high resistance

   Explanation: Increasing resistance decreases the current due to Ohm's Law.
