How many electrons are in a billion?

Answer: Originally Answered: How many electrons are in a 1 Coulomb charge? e=1.60•10^-19 C. 6.(6.25 billion billion) electrons.

What is the amount of current?

With electricity, we measure the amount of charge flowing through the circuit over a period of time. Current is measured in Amperes (usually just referred to as “Amps”). An ampere is defined as 6.electrons (1 Coulomb) per second passing through a point in a circuit.

What will happen to the current if the voltage is reduced to one half Brainly?

Answer. Explanation: Current is directly proportional to voltage; a halving of the voltage will halve the current. But current is also inversely proportional to the resistance; a doubling of the resistance will halve the current.

What will happen to the current if the voltage is decrease?

Answer: The current is directly proportional to the voltage and inversely proportional to the resistance. Any alteration in the voltage will result in the same alteration of the current.

What will happen to the current if resistance is?

Answer: 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.

What will happen if resistance is doubled while voltage is kept constant?

Answer. The current is inversely proportional to the resistance. This means that with a constant voltage source in the input, then current will decrease in half if resistance is doubled.

Which length of wire offers the greatest resistance?

Length. A short wire has a lower resistance than a long one*. Resistance is directly proportional to the length of the path through which current flows: R ∝ L. This means the longer the wire, the more resistance.

What are two things that will make the resistance of any wire increase?

Resistance increases with the temperature of the wire. The hotter wire has a larger resistance because of increased vibration of the atomic lattice. When a material gets hotter the atoms in the lattice vibrate more.

Why does the length of a wire affect resistance?

First, the total length of the wires will affect the amount of resistance. The longer the wire, the more resistance that there will be. More collisions mean more resistance. Second, the cross-sectional area of the wires will affect the amount of resistance.

How does the resistance of a wire depend on its length?

Resistance of a wire is directly proportional to the length of the wire. The resistance of a conductor depends on the number of collisions which the electrons suffer with the fixed positive ions while moving from one end to the other end of the conductor. Therefore, a longer conductor offers more resistance.

Is resistance directly proportional to the length of a wire?

The resistance of a wire is directly proportional to its length and inversely proportional to its cross-sectional area. Resistance also depends on the material of the conductor. The resistance of a conductor, or circuit element, generally increases with increasing temperature.
