The circuit that would glow brightest is b - A simple circuit with one bulb and two batteries

Electric circuit

This is the path for transmitting current. It usually consists of an electrical energy source and an electrical load.

In any circuit, the electrical power available is determined by the number of batteries available (energy source) and thus the current.

Ohm's law

Since we know according to Ohm's law V = iR where

  • V = voltage,
  • i = current and
  • R = load.

So, making i subject of the formula, we have i = V/R .

So, i ∝ 1/R this shows that the current is inversely proportional to the load.

Circuit that would glow brightest

  • a simple circuit with more current and less load would glow brightest.
  • So, having a simple circuit with two batteries increases the current in the circuit and having only one bulb means that there is less load in the circuit.
  • Thus, the circuit with one bulb and two batteries will glow brightest.

So, the circuit that would glow brightest is b - A simple circuit with one bulb and two batteries
