Why increasing the voltage applied to a wire can have the same effect on the current in the wire that decreasing the resistance of the wire does?
Increasing the voltage applied to a wire will increase the electric field, which in turn accelerates the charge carriers (usually electrons) in the wire, leading to an increase in current. Similarly, decreasing the resistance of the wire allows more current to flow for the same voltage applied, achieving a similar effect of increasing the current. Both actions result in a greater flow of charge carriers through the wire.
What is the relationship between power, voltage, and current, and how can it be expressed mathematically using the formula power equals voltage multiplied by current?
The relationship between power, voltage, and current can be expressed mathematically using the formula: Power Voltage x Current. This formula shows that power is directly proportional to both voltage and current. In other words, an increase in either voltage or current will result in an increase in power.
What happens to the current if the number of bulbs stays the same but you use more cells?
If you add more cells in series with the bulbs, the current will increase as the voltage across the bulbs increases. If you add more cells in parallel with the bulbs, the current will stay the same because the voltage of the cells does not increase when they are added in parallel.
How does changing the voltage in a circuit affect the current in the circuit?
Changing the voltage in a circuit will alter the current flowing through it. According to Ohm's Law, the current is directly proportional to the voltage in the circuit. Increasing the voltage will lead to an increase in current, and vice versa.
How do you change the current in a wire?
To change the current in a wire, you can adjust the voltage applied to the wire or change the resistance in the circuit. Increasing the voltage will increase the current as per Ohm's Law (I = V/R), while decreasing the resistance will also result in an increase in current.
What would be the effect of increasing the voltage of the battery?
Ohm's Law states that Voltage = Resistance (Ohms) * Current (Ampere). So when you increase voltage, you increase current.
If Three 12 volt batteries are connected in parallel what is the effect on the circuit?
There will be no effect on the voltage. That is the effective voltage will be only 12 volt. But there will be increase of current.
If we increase the current then what about the power factor?
The power factor depends on the phase angle between the voltage and current on a conductor. The amplitude of the current has no effect on it.
What is the effect of surge arrester on increase the voltage in medium voltage circuits?
What is the effect of surge arrested on increase the voltage in medium voltage circuits?
Should you increase voltage or resistance to increase flow in a circuit?
To increase (current) flow in a circuit you increase voltage (or decrease resistance). Ohm's Law: Current = Voltage divided by resistance
Will current increase if the voltage in a circuit is increased?
Ohm's Law states Voltage = Current x Resistance. Hence if voltage is increased and resistance is constant, current will increase proportionally to the rise in voltage.
Why current leads in capaciter?
Capacitors resist a change in voltage. It takes current to effect a voltage change, resulting in the current "leading" the voltage. Similarly, inductors resist a change in current. It takes voltage to effect a current change, resulting in the current "lagging" the voltage.
What is effect of voltage and current by changing the length of wire?
By changing the length of wire, say reducing it, the resistance will drop and that will increase current flow but the voltage is less likely to change V=IR.
What increases when current increases?
If current increases, then voltage also has to increase, assuming that resistance stay relatively the same. Power will also increase. Since power is the product of voltage and current, then the power increase would be the square of the voltage or current change.
Effect on voltage as current increases through constant resistance?
If the current is held constant, the voltage will decrease.
Why does increasing the voltage of a wire have the same effect on the current that decreasing the resistance has?
Ohm's Law is Voltage = Current x Resistance or written v - I x R. So if you raise the voltage and keep R the same current must increase to satisfy the equation. I = V/R. Similarly if you reduce R and keep V the same current will also increase proportionally.
When tempratere increase resistance increase and when resistance increase current decrease why?
That's what "resistance" is all about: reducing the current for a given voltage. In fact, you can DEFINE resistance as voltage divided by current.
