What happens to resistant if wire diameter is decreased?
If the wire diameter is decreased, the resistance of the wire will increase. This is because with a smaller diameter, there is less cross-sectional area for the electrical current to flow through, causing more hindrance and resulting in higher resistance.
What will happen to the current if double the length of the wire?
If you double the length of the wire while keeping the resistance constant, the current will halve because resistance is directly proportional to the length of the wire. This is described by Ohm's law (V = I * R), where V is voltage, I is current, and R is resistance.
What would happen to the current in a simple circuit if a bulb with a higher resistance were used?
If a bulb with higher resistance is used in a simple circuit, the total resistance in the circuit would increase. According to Ohm's Law (V=IR), with an increase in resistance, the current in the circuit would decrease since the voltage supplied remains constant.
How can air resistance be decreased?
Air resistance can be decreased by making the object more aerodynamic, such as by reducing its size or shaping it to minimize drag. Smooth surfaces and streamlined designs help to reduce turbulence and resistance. Additionally, reducing the object's speed can also decrease air resistance.
If resistance goes up how is current affected?
If resistance goes up in a circuit, the current will decrease. This is because Ohm's Law states that current is inversely proportional to resistance, meaning that as resistance increases, current decreases.
What happens to the power of an electric circuit of the resistance is decreased?
if the resistance is decreased and the current stays the same, then the power decreases.
What effect does decreased resistance have on a circuit?
resistance is the opposition to the flow of an electric current, therefore the current will decrease as the resistance increases. Resistance also creates heat. This is how the light globes in a circuit light up.
What happen to the current in a circuit if the resistance is increased?
If resistance is increased, current decreases. Ohm's Law: current equals voltage divided by resistance.
As the resistance in a series circuit is decreased the amount of current in the circuit increases or decreases?
Increases the total resistance
What happen to current in a circuit if the voltage is not charge but the resistance is doubled?
The current in the circuit will be decreased by half. Ohm's law states V=IR so, I=V/R. If R is doubled, then I= V/2R.
What would happen if the voltage in a circuit is decreased and the resistance remains constant?
Current draw would increase proportionally, heating up the wiring and wearing more on the load pulling the power.
If the decrease voltage and the resistance stays the same is current increased or decreased?
This question follows Ohm's law which states, "Current is directly proportional to the applied EMF (voltage) and inversely proportional to the current in the circuit. <<>> decreased
When resistance decreases what happens to current?
Based on the simplest Electrical Equation V = I * R,(reads: voltage equals current multiplied by resistance)then, rearranged I = V / R .As resistance decreases, current flow proportionately increases
When an ammeter is connected to measure current circuit current will decrease sightly because R total decreases after the meter is inserted?
Current will be decreased because of the resistance of the ammeter added to the circuit's resistance. In other words total resistance increases.
How you increase current by keeping voltage constant?
If you are referring to a simple circuit, you could add resistance throughout it. Increased resistance means decreased current flow yet the same voltage.
What is the effect on current if ohmic value of the resistance is decreased?
I = V/R (I is inversely related to R) Therefore, if R is decreased, I will increase if V is held constant.
If A conductor has a resistance of 0.8 ohms what will happen to its resistance if the temperature is decreased?
The resistance of a conductor is directly proportional to the resistivity of the conductor. since the resistivity of a conductor is decreases with decrease in temperature hence the resistance.
