What is the effect on current through a circuit of steady resistance when the voltage is doubled?

The current will increase and will flow more. If voltage increases, current must increase.

∙ 12y agoOhm's law: current is voltage divided by resistance, so doubling the voltage while holding the resistance constant will double the current.
Not asked, but answered for completeness sake; since power is voltage times current, doubling the voltage into a constant resistance will quadruple the power.

This can be proved by using ohms law, V=IR --> I=V/R, as the resistance is constant the R can be replaced by the number 1 therefore I=V/1 or I=V, hence if the voltage increases the current must also increase.

∙ 15y agoThe formula you are looking for is I = E/R. You supply some figures for Voltage (E) and Resistance (R).

If the resistance doubles, the current drops to 1/2 its original value.

Short circuits are dangerous because?
electricity always "wants" to take the easiest route, this is the route with the least resistance, this is why an insulator does not conduct electricity, it takes to much force for the electricity to travel through. a short circuit is when the easiest route is the wrong route i.e. the body of a lamp rather than the wiring of the lamp. the danger of a short circuit is dependent on the voltage and current of the electricity.
What is a closed path through which current can flow?
A closed path through which a current can flow is called a circuit. Electric Circuit:)
One way to make current is to use a what?
You can apply a potential difference across a wire to cause a current to flow through. Ohm's Law allows you to calculate the amount of current based on the voltage supplied and the resistance of the circuit. I = current V = voltage or potential difference R = resistance I = V/R
What is a parralell curcuit?
• In a parallel circuit, there are junctions in the circuit so the current can flow around the circuit in more than one way. • In a series circuit the current decreases as more bulbs are added. •In a parallel circuit, as more bulbs are added, the current increases. • This is because bulbs added in parallel offer less resistance
How are current and voltage affected in series and parallel circuits?
Voltage is Current multiplied by Resistance. The formulas for calculating the resistance in parallel and series circuits are: Resistors in Series: R(total)=R1+R2+R3+... Resistors in Parallel: 1/(Rtotal)=(1/R1)+(1/R2)+... Current is a measure of Coulombs of charge per unit of time or I=C/t The current depends on the circuit, whether it has capacitors or resistors, and the exact layout. Current 'flows' through wires in much the same way that water flows through pipes, so if the current meets some resistance (a resistor), some of the current will go through the resistor, but the rest will go through any other available path (like in a parallel circuit).
What determines the current in each branch of a parallel circuit?
The resistance of the component on that branch of the circuit, if the resistance is higher less of a proportion of the total current of the circuit will travel through that branch, however, if the resistance is low a higher proportion of the current will travel through that branch of the circuit. The voltage through each branch stays the same.
What determines the current in each branch of parallel of circuit?
The resistance of the component on that branch of the circuit, if the resistance is higher less of a proportion of the total current of the circuit will travel through that branch, however, if the resistance is low a higher proportion of the current will travel through that branch of the circuit. The voltage through each branch stays the same.
In a parallel ac circuit is the current additive?
Yes In parallel circuit , current entering into the circuit will be divided intodifferent paths ( resistances) . Amount of current flow depends upon the magnitude of resistance applied in the circuit. Total current after passing through the circuit will be the sum of all current through each resistance.
What determines the current ine each branch of parallel of circuit?
The resistance of the component on that branch of the circuit, if the resistance is higher less of a proportion of the total current of the circuit will travel through that branch, however, if the resistance is low a higher proportion of the current will travel through that branch of the circuit. The voltage through each branch stays the same.
How do resistance behave in parallel circuit?
in a parallel circuit resistance decreases increasing the current.
What is an equation for power?
Power = (energy used)/(time to use it)Power dissipated by an electrical circuit =(voltage across the circuit) x (current through the circuit)or(resistance of the circuit) x (square of the current through the circuit)or(square of the voltage across the circuit)/(resistance of the circuit)
Describe how a change in resistance would affect the current in a circuit?
As long as the voltage between the ends of the circuit remains constant, the current through the circuit is inversely proportional to the total effective resistance of the circuit.
Is the current pass through parallel short resistance?
no.because current always try to flow trough low resistance path.as short circuit has low resistance current pass trough short circuit
What is resistance do in a circuit?
lowers the amt of electrical current flowing through it.
Which property makes it difficult for current to pass through?
Resistance in the circuit makes it difficult for current to pass through.
If you double both the voltage and the resistance in a circuit what would be the effect on the current?
If you double the voltage in a circuit, the power is quadrupled, assuming the resistance stays the same.
In any parallel circuit within a combination circuit the greater current will flow through the?
lowest resistance
