Questions & Step-by-Step Solutions

In a circuit with a 10V battery and two resistors in parallel (4Ω and 6Ω), what is the voltage across each resistor?
Correct Answer: 10V
  • Step 1: Identify the components in the circuit. We have a 10V battery and two resistors (4Ω and 6Ω) connected in parallel.
  • Step 2: Understand what a parallel circuit means. In a parallel circuit, all components share the same voltage from the power source.
  • Step 3: Since the resistors are in parallel, the voltage across each resistor is equal to the voltage of the battery.
  • Step 4: The battery provides 10V, so the voltage across the 4Ω resistor is 10V.
  • Step 5: Similarly, the voltage across the 6Ω resistor is also 10V.
  • Step 6: Conclude that both resistors have 10V across them.
