Acircuit is a path along which electric current flows how would changing the battery in a circuit from 9 volts to 1.5 volts most likely affect the circuit

Reducing the voltage in circuit will affect the flow of current.

Explanation:

According to Ohm's Law: The electric current in closed circuit is directly proportional to the voltage applied to the circuit, where resistance offered by the electric circuit remains constant.

So, when we reduce the voltage in circuit from 9 volts from 1.5 volts the flow of the current will also get reduced in a circuit.

Hence ,reducing the voltage in circuit will affect the flow of current.

the answer is the first electromagnet (a). this is because it has more coils around the ferromagnetic material. increasing the number of coils increases the surface area in which the metal interacts with the current in the coil. this enables more atoms in the metal to become aligned hence becoming more magnetized.
