Because that's the definition of Ohm's law. Current = voltage / resistance.
Here's one way to think about it. Resistance is the degree of difficulty in moving charge from one place to another. If you increase that resistance, it is harder to move the charge. Current is rate of flow of that charge, hence current goes down.
If resistance increases and voltage stays the same, then current decreases. Ohm's Law: Current equals Voltage divided by Resistance.
Ohm's Law says that Voltage = Current x Resistance (Load). Therefore Current = Voltage / Resistance and as resistance decreases current increases and as resistance increases current decreases.
Their relationship is only dependent on the voltage lost across that resistor; voltage equals resistance times current, so increasing the current for a given voltage will require a decrease in the resistance, and vice versa.
The physical equation governing voltage is V = IR, where V is voltage, I is current, and R is resistance. If V remains constant while R is increased, I or current must decrease. Increasing the resistance in a circuit is simply introducing a material that further resists or impedes the electron flow (current), thus current decreases.
If the current is held constant, the voltage will decrease.
If the resistance increases, while the voltage stays the same, current will decrease. Current = voltage divided by resistance
Resistance increases as temperature increases. If Voltage is held constant then according to Ohm's Law Voltage = Current x Resistance then current would decrease as resistance increases.
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
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 resistance increases and voltage stays the same, then current decreases. Ohm's Law: Current equals Voltage divided by Resistance.
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.
it increases because increasing load means more output power, more output power means more current
First, this statement stands as long as voltage is constant. If you held the current constant then power would increase as resistance increases.V=IR. For a fixed voltage if you increase the resistance (R) then the current (I) will decrease - following the formula.Power = VI so as the resistance increases the value of VI (power) decreases as V is constant and I gets smaller.Therefore the power is decreasing as the resistance increases (when voltage is held constant).Hope this helps.
Current will be decreased because of the resistance of the ammeter added to the circuit's resistance. In other words total resistance increases.
The only way current can increase while resistance in a circuit increases is if voltage, which is the force that causes electric current, increases.
As the resistance increases the temperature will also increases....
Ohm's Law says that Voltage = Current x Resistance (Load). Therefore Current = Voltage / Resistance and as resistance decreases current increases and as resistance increases current decreases.
