What can you infer about the voltage of the two circuits tested?*1 pointThe voltage in the two circuits is zero.The voltage is higher in the circuit with two dry cells.The voltage in the two circuits are the same.The voltage is higher in the circuit with one dry cell.

The battery supplies the energy in electric circuits. The chemical energy in the battery is transformed to electrical energy. This electrical energy moves the charges in a circuit. The higher the number of battery used, the greater the voltage in a circuit.What can you infer about the voltage of the two circuits tested?*1 pointThe voltage in the two circuits is zero.The voltage is higher in the circuit with two dry cells.The voltage in the two circuits are the same.The voltage is higher in the circuit with one dry cell.

In which circuit did you observe a higher registered electric current?*1 pointThe amount of electric current in the two circuits is zero.Circuit with two dry cellsCircuit with one dry cellThe amount of electric current in the two circuits are the same.

In which circuit did you observe a brighter light bulb?*1 pointCircuit with two dry cellsCircuit with one dry cellThe brightness of the bulbs in the two circuits are the same.The bulb did not light up in any of the circuits.
