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.
What else can I help you with?
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 voltage impressed across a circuit is constant but the resistance increases by a factor of 7 By what factor does the current change?
A: 1/7
If the resistance in a circuit is doubled while the voltage remains the constant the current is?
It is halved. coz voltage=current * resistance
As the resistance in a series circuit is decreased the amount of current in the circuit increases or decreases?
Increases the total resistance
Will doubling the resistance in a circuit halve the current if voltage is held constant?
If resistance is halved while voltage remains constant, the current will double.
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.
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.
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).
What happens to the voltage if the current increases?
Yes, if the resistance remains constant. Power is voltage times current, and current is voltage divided by resistance, so power is voltage squared divided by resistance. In essence, the power increases as the square of the voltage.
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
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.
How the current in a circuit changes if the voltage in the circuit is decreased and the resistance remains the same?
If the ratio of voltage to current is constant, then the circuit is obeying Ohm's Law. If the ratio changes for variations in voltage, then the circuit does not obey Ohm's Law.
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
If the voltage impressed across a circuit is constant but the resistance increases by a factor of 7 By what factor does the current change?
A: 1/7
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.
