current change with resistance as, anything which opposes flow of current is called resistor is circuit, now we use battery to give potential across the circuit, potential just ensure the continuous flow of charge from higher to lower potential (water flows from high PE to low PE), while resistance opposes the flow of charge and thereby effecting the value of current, it's practically found that more is the resistance, less is the current flowing through resistance, this is indirectly observed from ohm law V=IR.
What else can I help you with?
How does the changing the battery voltage affect the current?
If voltage varies then current varies with constant resistance.
How does loading effect affect flow of current?
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.
Reducing voltage in a circuit does not affect resistance?
Reducing voltage in a circuit does not directly affect resistance. It affects current. Resistance is an independent variable.Ohm's law: voltage equals current times resistance.However, reducing voltage and/or current does reduce power, which reduces temperature, which can change resistance because resistance is usually affected to some degree by temperature.
Why is it capacitance does not affect current in a Direct Current circuit?
Capacitors resist a change in voltage, proportional to current and inversely proportional to capacitance. In a DC circuit, the voltage is not changing. Therefore, after equilibrium is reached, there is no current flowing through the capacitor.
How does increasing the resistance affect the current?
Increasing resistance decreases current.
How does the changing the battery voltage affect the current?
If voltage varies then current varies with constant resistance.
How does the voltage applied to a circuit affect the current flowing through the wire?
Voltage is equal to the Current multiplied by the Resistance.Without changing the resistance, increasing the applied voltage in a circuit will increase current flow. There is a simple, direct relationship between voltage and current. Double the voltage, twice the current will flow. Triple the voltage, and the current will triple. As voltage (E) equals current (I) times resistance (R), when resistance is fixed, what happens to voltage will happen to current.
How does loading effect affect flow of current?
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.

How does changing the voltage in a circuit affect the current in the circuit?
Changing the voltage in a circuit will alter the current flowing through it. According to Ohm's Law, the current is directly proportional to the voltage in the circuit. Increasing the voltage will lead to an increase in current, and vice versa.
What happen to voltage sensitivity if current sensitivity is increase of agalvanometer?
If current sensitivity of a galvanometer is increased, the voltage sensitivity remains the same. Voltage sensitivity depends on the resistance of the galvanometer coil, while current sensitivity depends on the number of turns in the coil. Therefore, changing current sensitivity does not affect voltage sensitivity.
How can electric current be changed in Omh's Law?
Ohm's Law: V = IR Solving for current: I = V/R To affect the current, you can either change the voltage (more voltage --> more current), or the resistance (more resistance --> less current).
What does power divided by speed equal?
Ohm so correctly said: Voltage divided by current equals resistance. Voltage divided by current will tell you the value of a circuit's resistance. But resistance is not affected by either voltage or current. It is determined by the length, cross-sectional area, and resistivity (type of conducting material) of the conductor. Resistivity is, in turn, affected by temperature. So voltage divided by current tells you what the resistance happens to be - changes in voltage or current do not affect resistance.
Does the thickness of a wire affect the voltage?
The thickness of a wire, also known as gauge size, can affect the resistance of the wire which in turn can affect the voltage drop across the wire when current flows through it. Thicker wires have lower resistance, resulting in less voltage drop compared to thinner wires for the same current flow.
What factors determine the size of a current?
The size of a current is determined by the voltage applied, the resistance of the circuit, and Ohm's Law (current = voltage / resistance). The type of conductor material used, the temperature, and the cross-sectional area of the conductor also affect the size of a current.
Resistance of a copper conductor will decrease with an increase of applied voltage?
Resistance is affected by the length, cross-sectional area, and resistivity of the conductor. The resistivity, in turn, is affected by temperature. So only by changing one of these four factors will the resistance of a conductor change. Changing voltage will have no affect upon the conductor's resistance.
How does resistance affect a circuit?
Resistance in a circuit restricts the flow of electrical current, leading to a decrease in the overall current in the circuit. This results in a drop in voltage across the components in the circuit and the generation of heat as energy is dissipated due to the resistance. Increasing resistance can reduce the efficiency of the circuit by impacting the voltage and current levels.
