If the voltage doubles while the resistance remains the same, the power increases by a factor of four.
Power = voltage times current
Current = voltage divided by resistance
So, power = voltage squared divided by resistance
This has nothing to do with being in a series circuit. It is simply Ohm's Law and Joule's Laws.
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
V = IR Where, V = voltage I = current R = resistance Thus if resistance is increased with constant voltage current will decrease
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.
Current decreasesWhen voltage remains constant and resistance increases the current in the circuit will reduce.More informationV=IRwhere V is voltage,I is current andR is resistance.From the above equation,R=V/I, and hence resistance is indirectly proportional to current.Therefore, an increase in resistance would have the effect of decreased current.NB: this holds true only as long as the voltage remains constant.Another opinionHowever, this is only true in the case of a circuit connected in series.When circuits are connected in parallel, the opposite happens. If there is an increase in the amount of resistors in parallel, the total resistance of the circuit then decreases and the current increases subsequently.Yet another viewNo, that's not stated right.If more resistors are added in parallel - so that the circuit's overall total resistance decreases and its total current increases - that is NOT in any way the opposite of what this question is asking about...Let's make this crystal clear, so that there is no confusion: "an increase in the amount of resistors" is NOT the same as "an increase in resistance".So a parallel circuit behaves EXACTLY the same as a series circuit: if its overall resistance increases, the overall current going through the parallel circuit decreases AND if its overall resistance decreases, the overall current going through the parallel circuit increases.Actually, the second opinion is correctIn a parallel circuit, there are more branches to allow electrons back to the power supply, so current increases. With more resistors in a circuit, the overall resistance in a parallel circuit DECREASES.In a series circuit, current is the same throughout. So if more resistors are added, resistance INCREASES and so current DECREASES.
it remains same i=voltage/total resistance
It is halved. coz voltage=current * resistance
Current increases if the voltage remains constant.
When the frequency is doubled, the resistance of a circuit remains unchanged. Resistance in a circuit is independent of frequency and is determined by the material and physical dimensions of the resistor.
In a parallel circuit, the total resistance remains the same when the voltage applied is doubled. Each branch in the parallel circuit will experience the same increase in voltage, but their individual resistances will remain constant.
If resistance is doubled in a circuit with constant voltage, Ohm's Law (V=IR) states that current (I) would be halved since the voltage is constant. This is because the relationship between resistance and current is inversely proportional.
nothing
If the voltage in a circuit were doubled, the current would also double according to Ohm's Law (I = V/R), assuming the resistance in the circuit remains constant. This is because current is directly proportional to voltage when resistance is held constant.
If the potential difference across a circuit is doubled, the current flowing through the circuit will also double, assuming the resistance remains constant. This is because Ohm's Law states that current is directly proportional to voltage when resistance is held constant.
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.

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.
