What happens to the resistance if potential difference is doubled?

On doubling of the potential difference across the ends of a conductor e, the current flowing through it also gets doubled, and when the potential difference is halved, the current also gets halved. On doubling of resistance, the current gets halved, and if the resistance is halved, the current gets doubled.

What happens to the current if the resistance is half?

But current is also inversely proportional to the resistance; a halving of the resistance will double the current.

What will happen to the current in a circuit if the resistance decreases?

This equation, i = v/r, tells us that the current, i, flowing through a circuit is directly proportional to the voltage, v, and inversely proportional to the resistance, r. In other words, if we increase the voltage, then the current will increase. But, if we increase the resistance, then the current will decrease.

What will be the current in the circuit if resistance is doubled?

question_answer Answers(1) If the resistance is doubled by applying the constant potential difference the current becomes the half of the previous.

What will happen to current passing through a resistor if the potential?

Answer: g. Inew = 24 mA (Current is directly proportional to voltage; a doubling of the voltage will double the current. But current is also inversely proportional to the resistance; a doubling of the resistance will halve the current.

When resistance is 2 ohm and the current passing through the circuit is 0.5 A then potential difference is?

When a current of 0.5 A is passed through two resistances in series, the potential difference between the ends of the series arrangement is 12.5 V.

When resistance is made half at constant voltage current will become?

If the voltage is constant, the resistance of the circuit is halved. That is, it becomes R / 2. Thus by keeping the p.d. constant, the resistance of a circuit is halved and the current is doubled.

What happens to the resistance of circuit if current through it is doubled 1 point resistance is doubled resistance becomes half resistance remains same None?

Physical Science if resistance is doubled then the current would be halved as resistance is inversely proportional to the current flowing in a circuit. that is if the resistance is doubled the current would be halved.

When voltage across a resistor is doubled the current will?

This is equivalent to I=2(VR) . Therefore, we can see that if the voltage doubles, the current also doubles for the same resistance.

When current passes through an ohmic resistor the potential difference across the resistor?

Question: dissipates When current passes through an ohmic resistor, the potential difference across the resistor lower so that ts at the end where current enters the resistor and at the end where it exists. Resistance therefore energy by converting higher electric potential energy into kinetic into thermal.

What happens when a battery is connected to a resistor?

2. A battery is connected to a resistor. Increasing the resistance of the resistor will A. increase the current in the circuit. B. decrease the current in the circuit. C. not affect the current in the circuit. 3. A battery is connected to a resistor. As charge flows, the chemical energy of the battery is dissipated as A. current.

How do you calculate the current flowing through a resistor?

Calculate the current flowing through each resistor. The current flowing through each resistor is determined using Ohm’s law. where I is the current, R is the resistance, and V is the voltage. Four 28-Ω resistors are connected in series to a 18-V battery of negligible internal resistance.

What is the power dissipated when a resistor is connected?

A resistor is connected to a 3.0 V battery; the power dissipatedin the resistor is 1.0 W. The battery is traded for a 6.0 V battery. The power dissipated by the resistoris now A. 1.0 W B. 2.0 W C. 3.0 W D. 4.0 W Multiple choice Problem 1: An electric blanket has a wire that runs through the interior.

How does current travel through a circuit with two batteries?

For your situation, let’s imagine the circuit has one battery connected in series with two bulbs, A and B. In direct current, which is the current you have with a battery (as opposed to alternating current with a generator), charges leave the battery and travel around the circuit.
