Question

 If the Voltage is increased and the resistance stays the same, Current will
1)increase
2) decrease
3)stay the same
4) none of these​

Answer 1

Ohm's law states that the electrical current (I) flowing in an circuit is proportional to the voltage (V) and inversely proportional to the resistance (R). Therefore, if the voltage is increased, the current will increase provided the resistance of the circuit does not change

Answer 2

If the Voltage is increased and the resistance stays the same, Current will 1) increase.

Explanation:

• An electric current is a flow of electric charge in a circuit. Here, the electric charge is electron in the conductor.  It is the rate of charge flow past a given point in an electrical circuit.

• If a potential difference is applied on the electrons for encouraging a movement in a particular direction, then all electrons drift in same direction, although still in random manner, but there is an overall movement in one direction. This is termed as flow of current.

• Resistance is the tendency of a material to resist the flow of electrical current. SI unit of resistance is ohm (Ω).

According to Ohm's Law: Potential difference is directly proportional to the current flowing in the conductor.

• $V$∝$I$

• $V=IR$, where $V$ is the applied external potential difference, $I$ is the current flowing and $R$ is the resistance of the conductor.

So, when voltage is increased, current also increases if resistance is kept constant.
