What else can I help you with?
When current remains constant and resistance increases the voltage in the circuit will?
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.
Why isn't resistance constant?
If measuring resistance of materials or resistors by themselves(not soldered into a circuit board) resistance is constant. If measuring resistance of a circuit then it could fluctuate with the components functioning in the circuit.
As the resistance in a series circuit is decreased the amount of current in the circuit increases or decreases?
Increases the total resistance
Does increasing the resistance increase the electric current?
If the current through a pure metallic conductor causes the temperature of that conductor to rise, then its resistance will increase. A practical example of this is an electric lamp. The cold resistance of a lamp is very much lower than the hot resistance.
If the resistance in a circuit is doubled while the voltage remains the constant the current is?
It is halved. coz voltage=current * resistance
What increases when the resistance of an electrical circuit decreases?
Current increases if the voltage remains constant.
How does current vary with the resistance in the circuit if the voltage is constant?
Inversely. As resistance increases, current dereases; given that the applied voltage is constant.
What is the relationship between current and resistance in a circuit when the voltage is kept constant?
In a circuit with constant voltage, the relationship between current and resistance is inversely proportional. This means that as resistance increases, the current flowing through the circuit decreases, and vice versa.
Time constant of an RC circuit increases if the value of the resistance?
increases. Time constant, denoted by τ, is equal to the product of resistance (R) and capacitance (C), τ = RC. If the resistance increases, it will take longer for the capacitor to charge or discharge, resulting in a longer time constant.
Does the current ina circuit increase with increase in temperature?
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.
When current remains constant and resistance increases the voltage in the circuit will?
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 resistance goes up does current go down?
At constant temp.& pressure,on the same circuit,with potential difference unchanged,current reduces if resistance increases.(Ohm's law).
Why isn't resistance constant?
If measuring resistance of materials or resistors by themselves(not soldered into a circuit board) resistance is constant. If measuring resistance of a circuit then it could fluctuate with the components functioning in the circuit.
As the resistance in a series circuit is decreased the amount of current in the circuit increases or decreases?
Increases the total resistance
What will happen in a circuit if the voltage does not change but the resistance in the circuit increases?
If the resistance increases, while the voltage stays the same, current will decrease. Current = voltage divided by resistance
What is the relationship between current and voltage in an electrical circuit?
The relationship between current and voltage in an electrical circuit is described by Ohm's Law, which states that the current flowing through a circuit is directly proportional to the voltage applied across it, and inversely proportional to the resistance of the circuit. In simpler terms, as the voltage increases, the current flowing through the circuit also increases, assuming the resistance remains constant.
