Take a look at Ohm's Law, usually written as V=IR. Solving for current: I = V/R. That means that a lower resistance will result in a larger current.
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.
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.
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.
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 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.
if the resistance is decreased and the current stays the same, then the power decreases.
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.
If resistance is increased, current decreases. Ohm's Law: current equals voltage divided by resistance.
Increases the total resistance
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.
Current draw would increase proportionally, heating up the wiring and wearing more on the load pulling the power.
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
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
Current will be decreased because of the resistance of the ammeter added to the circuit's resistance. In other words total resistance increases.
If you are referring to a simple circuit, you could add resistance throughout it. Increased resistance means decreased current flow yet the same voltage.
I = V/R (I is inversely related to R) Therefore, if R is decreased, I will increase if V is held constant.
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.
