Responses

If the voltage of circuit A is equal to the voltage of circuit B, then the current in circuit A is equal to the current in circuit B.
If the voltage of circuit A is equal to the voltage of circuit B, then the current in circuit A is equal to the current in circuit B.

If the voltage of circuit A is equal to the voltage of circuit B, then the current in circuit A is less than the current in circuit B.
If the voltage of circuit A is equal to the voltage of circuit B, then the current in circuit A is less than the current in circuit B.

If the current in circuit A is less than the current in circuit B, then the voltage in circuit A is less than the voltage in circuit B.
If the current in circuit A is less than the current in circuit B, then the voltage in circuit A is less than the voltage in circuit B.

If the current in circuit A is equal to the current in circuit B, then the voltage in circuit A is less than the voltage in circuit B.

Circuit 4 will have the greatest electric current because it has the lowest resistance and the highest voltage, which results in a higher current flow according to Ohm's Law (I = V/R).

If the current in circuit A is less than the current in circuit B, then the voltage in circuit A is less than the voltage in circuit B.

This statement is correct because according to Ohm's Law (V = I*R), if the current in circuit A is lower than circuit B, and the resistance in circuit A is higher than circuit B, then the voltage drop in circuit A will also be less than in circuit B.

It limits the amount of electrical energy that can pass through a circuit.

This statement best defines the resistance of an electric circuit. Resistance is a property of a material or component that limits the flow of electrical current through it, thereby restricting the amount of electrical energy that can pass through the circuit.

A resistor in the circuit is broken.

If the measured current in the circuit is higher than the expected current, it could be due to a broken or damaged resistor in the circuit, reducing the resistance and allowing more current to flow. This would explain the higher current reading by the electrician.
