What will happen to the current if the charge increases?

More collisions means it takes longer for the charge to ‘get through’ the component. The charge is moving slower and so the current is lower. Or, is it that the speed is always the same and that somehow if we have more resistance then it means there is just less charge able to flow, hence a lower current.

What happens when current is constant?

If the current is held constant, an increase in voltage will result in an increase in resistance. Alternately, an increase in current while holding the voltage constant will result in a decrease in resistance.

What is the relationship of current and charge?

An electric current is a flow of charged particles. In metal conductors the charged particles are free electrons….The relationship between current I and quantity of charge Q.

I =	I = Q ÷ t
Q = It	Q = I x t
t =	t = Q ÷ I

What happens to current as voltage is increased at constant resistance?

The current is directly proportional to the voltage and inversely proportional to the resistance. This means that increasing the voltage will cause the current to increase, while increasing the resistance will cause the current to decrease.

Why does current increase when voltage increases?

As voltage increases the energy of electrons increases and due to which it’s drift velocity also increases and the rate of passing electrons through the conductor increases which is cause of current flowing and due to this increase in rate of flow , the current also increases..

What is charging current and what are its effects?

It reduces the load current, due to which line losses decreases, and hence the efficiency of the line is increased. It improves the power factor of the transmission line. Charging current improves the load capacity of the line. It improves the voltage regulation of the line because the voltage drop is quite small.

Does constant voltage mean constant current?

Constant voltage luminaires require a steady voltage to be supplied from the driver eg 12 or 24 Volts. For these lights the voltage is fixed by the driver but the current may vary. Although the voltage stays constant, the current required from the driver goes up with the number of lights.

Is current inversely proportional to charge?

Yes, Ohm’s law states that “At constant temperature, current is directly proportional to voltage applied”.

Why is the current constant in a series circuit?

Since the voltage is decreasing the resistance is also decreasing so the current remains constant across all parts of the series circuit. If one component is in series with another, it will have the same current as the other. The varying component is the voltage across the components.

What happens to the voltage across a capacitor as time increases?

An ideal capacitor will not get fully charge, that means as time increases as current enters to it, the voltage also increases. In this way, as time approaches infinity, the voltage across it will also be to infinity. In graph, a constant current flowing into a capacitor will result also to a constantly increasing potential at its plates.

What happens when current is increased in a circuit?

If current (I) is increased and the charge Q is fixed (Charge is fixed if the power supply is from power cells like battery). Time will be decreased. The charges are moving faster! Because numbers of charge are fixed by the size of battery. Imagine a four lanes road.

What is the relationship between current and voltage?

Current is the amount of charge that is flowing through a component per unit of time. For a given voltage, Ohm’s law tells us that if we increase the resistance, then the current must decrease.
