Question

Total current is the sum of the current across each resistor in

  1. Series connection
  2. Parallel connection
  3. Both a and b
  4. None of the above

hintHint:

In a series circuit, all the components are arranged in a single line. In a parallel circuit, all the components are arranged parallel to each other. If more than one resistor is connected in series, the voltage across each resistor is not the same though the current flow is the same throughout the circuit.

The correct answer is: Parallel connection


    • In a series circuit, all the components are arranged in a single line. In a parallel circuit, all the components are arranged parallel to each other. If more than one resistor is connected in series, the voltage across each resistor is not the same though the current flow is the same throughout the circuit.
    • Parallel resistors do not each get the total current; they divide it. The current entering a parallel combination of resistors is equal to the sum of the current through each resistor in parallel
