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.

A student experiments with a simple circuit by testing it with a 1.2 - volt battery. Next, the student tests the same circuit with a 3.6-volt battery instead. The student records the voltage, resistance, and current of both trials in a table.Trial Number Voltage (volts) Resistance (ohms) Current (amperes)Trial 1 1.2 800 0.0015Trial 2 3.6 800 0.0045Based on the experiment, which claim can the student make about the relationship between voltage, resistance, and current?A When voltage is increased, the current will decrease if the resistance remains constant.B When voltage is increased, the current will increase if the resistance remains constant.C When resistance is increased, the voltage and current will also increase.D When resistance is increased, the voltage and current will both decrease.

Explain the purpose of a battery in a circuit.

Identify if each statement is true or false (3 marks)a) Voltage is the flow or amount of electric chargeb) Current is a measure of the amount of electrical energy gained or lost by electric charge as it moves through the circuit.c) Voltage is also known as potential difference because it measures a change in the potential (stored) energy of charge as it moves between one place and another.
